### Asynchronous JavaScript
Unlocking Asynchronous JavaScript: Navigate the world of async programming. Understand promises, async/await, and callbacks, mastering the art of handling asynchronous tasks in JavaScript.
- ASYNC JS
- setTimeout
setTimeout(() => {
console.log("Timeout runs !!!");
}, 1000);
- setInterval
setInterval(() => {
console.log("Interval runs !!!");
}, 1000);
- Fetch API (AJAX API request)
fetch("https://randomuser.me/api")
.then((data) => data.json())
.then((res) => console.log(res));
- Axios (or other HTTP libraries)
- use CDN for using axios
axios
.get("https://randomuser.me/api")
.then((res) => console.log(res.data.results[0]));
- callbacks
function abcd(a, b) {
b();
}
abcd(1, function () {
console.log("abcd runs");
});
- Promises
const promise1 = new Promise(function (resolve, reject) {
let a = 10;
if (a == 10) {
resolve("value match");
} else {
reject("value does not match");
}
});
promise1
.then((result) => {
console.log(result);
})
.catch((err) => {
console.log(err);
});
- Async/Await
async function abcd() {
const data = await fetch(`https://randomuser.me/api`);
const result = await data.json();
console.log(result.results[0]);
console.log(result.results[0].name.first);
}
abcd();
- Event Loop : It checks whether main stack is empty or not and perform asynchronous tasks according to it
#### These terms store aysnc task
- callback Queue
- Microtask Queue
- Web APIs
- Callbacks vs Promises vs Async/Await
#### Question: https://randomuser.me/api is url se data lekar aao and usey console par show karo
- using callback
function dataFetch(url, callback) {
fetch(url)
.then((res) => res.json())
.then((result) => {
callback(result);
});
}
dataFetch(`https://randomuser.me/api`, function (data) {
console.log(data);
});
- using promises
function dataFetch(url) {
const data = new Promise((resolve, reject) => {
fetch(url)
.then((raw) => raw.json())
.then((res) => resolve(res));
});
return data;
}
dataFetch(`https://randomuser.me/api`).then((res) => console.log(res));
- using async await
async function dataFetch(url) {
const data = await fetch(url);
const result = await data.json();
return result;
}
async function dataPrint(url) {
const data = await dataFetch(url);
console.log(data);
}
dataPrint(`https://randomuser.me/api`);
- Generators
// aap program ke flow ko pause kr skte ho (execution) and bol sakte ab agla step karo
// function* printNum() {
// console.log("started");
// yield 1;
// console.log("pehle chl chuka hai");
// yield 2;
// console.log("dusra chl chuka");
// yield 3;
// console.log("chotha chl chuka");
// yield 4;
// }
// const ans = printNum();
// console.log(ans.next().value);
// console.log(ans.next().value);
// console.log(ans.next().value);
- question - 10print
function* allNums() {
for (let i = 1; i < 11; i++) {
yield i;
}
}
// allNums().next();
// console.log(allNums().next().value);
const gen = allNums();
console.log(gen.next());
console.log(gen.next());
- Error Handling in Asynchronous Code (try,catch,finally)
- Web Workers
- usually humara code single thead par chlta hai par kai baar kuchh bade calculations perform karne pad jate hai jiski wajah se aapka main thread busy ho jaata hai yaa fir wo kaafi jaada loaded ho jaata hai aur aapke baki tasks ki performance kam ho jaati hai
- ap chaaho to apna koi task web worker ko bhej sakte ho jo ki doosre thread mein usko perform karega and aapka main thread efficiently baaki cheejo ko handle kar paayega
- aap apni main js file se data send kr skte ho and aap worker file data accept karoge and jo perform karna hai karoge and waha se data waapis main file bhejoge and main file main waapis accept kroge
// add numbers
const nums = Array.from({ length: 10000 }, (_, b) => b + 1);
const worker = new Worker("worker.js");
// data send
worker.postMessage(nums);
worker.onmessage = function (data) {
console.log(data.data);
};
- worker.js file
onmessage = function (data) {
// console.log(data.data);
const sum = data.data.reduce((acc, item) => item + acc, 0);
// console.log(sum);
postMessage(sum);
};

10. Show a progress bar which shows how much page has been scrolled.
### Real Life Developer Problems
- Developer Problems: Problem 1
- DEVELOPER PROBLEMS
- Debugging a TypeError: Cannot read property 'X' of undefined:
let obj = {};
obj.name; // no error
obj.name.age; // error
// Uncaught TypeError: Cannot read properties of undefined (reading 'age')
- Use optional chaining
obj?.name;
obj?.name?.age;
- Developer Problems: Problem 2
- Working with Local Storage
- local Storage ek aisa space hai browser ke pass jismein tum data store kardo to data stored hi rehta hai, aap chaahe to browser band krdo, refresh krdo ya kuchh bhi karo aapka data stored rahega jab tak aap khud usey delete naa kar de
- local storage poore browser ka hota hai ya website ka, ls hota to browser ka part hai par data store ye website ke naam se karta hai
localStorage.setItem("name", "Lucky Kashyap");
localStorage.setItem("age", 23);
localStorage.setItem('block',true);
- web site open or not if block true or false
- ek button banao jisse aap user block kardo ab jab bhi wo website khole use screen par blocked dikhey, nahi to website show ho and ek button jisse wo unblock ho
- Developer Problems: Problem 3
- Handling Asynchronous Operations
- ek button banao and us button ke click par aapko ek user lekar aana hai random tareeke se and usey add karna hai DOM mein
call Api
// random user api
function getNewCard() {
fetch(`https://randomuser.me/api`)
.then((raw) => raw.json())
.then((result) => {
// console.log(result.results[0]);
const { name, email, gender, picture } = result.results[0];
// console.log(name, email, gender);
document.querySelector(
"#parent"
).innerHTML += `
${name.first}
${gender}
${email}
Lorem ipsum dolor sit amet consectetur, adipisicing elit.
Repellat voluptates omnis doloribus perferendis?
`;
// return result;
});
}
document.querySelector("button").addEventListener("click", () => {
getNewCard();
});
- Developer Problems: Problem 4
- blocking scroll until something happens
document.querySelector("#hide").addEventListener("click", () => {
document.body.classList.toggle("overflow-hidden");
});
- Developer Problems: Problem 5
- custom tooltip
document.querySelector("#hide").addEventListener("mouseenter", () => {
document.querySelector(".tooltip").style.display = "initial";
});
document.querySelector("#hide").addEventListener("mouseleave", () => {
document.querySelector(".tooltip").style.display = "none";
});
### GSAP, ScrollTrigger, Locomotive - Fun Stuff
This introductory topic sets the stage for an exciting journey into advanced web animation techniques. GSAP (GreenSock Animation Platform), ScrollTrigger, Locomotive, and other tools are introduced as powerful resources for creating dynamic and engaging web animations.
-GSAP Basics:
GSAP Project :
Include GSAP Using CDN link
gsap.to('selector',{properties})
gsap.from(".nav h3", {y: -50, opacity: 0,duration: 1,delay: 0.5,stagger: 1,});
ScrollTrigger UseCase :
### GSAP - Understanding Pin Property in ScrollTrigger
gsap.to(".page2 img", {
width: "100%",
scrollTrigger: {
trigger: ".page2",
scroller: "body",
markers: true,
start: "top 0",
end: "top -100%",
scrub: 2,
pin:true
},
});
Project ShowCase :
- Text Scroll Effect
gsap.to(".page2 h1", {
transform: "translateX(-125%)",
scrollTrigger: {
trigger: ".page2",
scroller: "body",
scrub: 2,
pin: true,
start: "top 0",
end: "top -100%",
},
});
Project ShowCase:
### Locomotive- All in One Video
- Learning Smooth Scrolling Effects
- Include CDN links to index.html file
// CSS file
// locomotive JS File
- In script.js file :
// locomotive scrolling
import LocomotiveScroll from "locomotive-scroll";
const scroll = new LocomotiveScroll({
el: document.querySelector(".main"),
smooth: true,
});
- It applies smooth scrolling
### GSAP, ScrollTrigger, Locomotive Configure
Include CDN Links :
- To Apply Locomotive Don't give width & height to wrapper/container
- Locomotive Smooth Scrolling :
- To use scrolltrigger with locomotive you need include some JS Code
gsap.registerPlugin(ScrollTrigger);
// Using Locomotive Scroll from Locomotive https://github.com/locomotivemtl/locomotive-scroll
const locoScroll = new LocomotiveScroll({
el: document.querySelector(".main"),
smooth: true,
});
// each time Locomotive Scroll updates, tell ScrollTrigger to update too (sync positioning)
locoScroll.on("scroll", ScrollTrigger.update);
// tell ScrollTrigger to use these proxy methods for the ".main" element since Locomotive Scroll is hijacking things
ScrollTrigger.scrollerProxy(".main", {
scrollTop(value) {
return arguments.length
? locoScroll.scrollTo(value, 0, 0)
: locoScroll.scroll.instance.scroll.y;
}, // we don't have to define a scrollLeft because we're only scrolling vertically.
getBoundingClientRect() {
return {
top: 0,
left: 0,
width: window.innerWidth,
height: window.innerHeight,
};
},
// LocomotiveScroll handles things completely differently on mobile devices - it doesn't even transform the container at all! So to get the correct behavior and avoid jitters, we should pin things with position: fixed on mobile. We sense it by checking to see if there's a transform applied to the container (the LocomotiveScroll-controlled element).
pinType: document.querySelector(".main").style.transform
? "transform"
: "fixed",
});
// each time the window updates, we should refresh ScrollTrigger and then update LocomotiveScroll.
ScrollTrigger.addEventListener("refresh", () => locoScroll.update());
// after everything is set up, refresh() ScrollTrigger and update LocomotiveScroll because padding may have been added for pinning, etc.
ScrollTrigger.refresh();
gsap.from(".page1 .box", {
scale: 0,
duration: 1,
delay: 1,
opacity: 0,
rotate: 360,
});
gsap.from(".page2 .box", {
scale: 0,
duration: 1,
// delay: 1,
opacity: 0,
rotate: 360,
scrollTrigger: {
trigger: ".page2 .box",
scroller: ".main",
start: "top 50%",
markers: true,
},
});
Use Locomotive & GSAP ScrollTrigger Both:

# React JS
- JavaScript Library for creating user interfaces.
### Introduction To React JS
Embark on the React JS journey! Discover the essentials in 'Introduction to React JS'. Uncover the basics and get started with this popular JavaScript library for building user interfaces.
- UI Library
- for solving the real time problem (facebook build this cool library)
- for notification update on real time basically (2013).
### React JS Theory & History
Understanding React JS: Delve into its theory and historical roots. Explore the foundational aspects and historical development of React JS
- react -> lang X
- react -> framework X
- react -> technology X
- react -> library
- facebook - 2013
- 2015 - open source
#### Virtual DOM
- Copy of real DOM
jab websites par khhob sare change hote hai to khoob saara repaint hota hai wo bhi wo elements jo badle bhi nahi, aur ye website ko slow down kar deta hai, is cheej se bhi bachne ke liyein facebook ne react create ki gyi
- likes count, notification count side by side (change/update)
- when ever there is change in UI the DOM repaint or rerender things
- This is not the case with virtual DOM or with React. React solves this problem of not repaint Those part which was not updated or changed only re render things which are updated.
### React JS - Essentials - Everything you need to learn
Core Foundations of React JS: 'Essentials - Everything You Need to Learn'. Delve into essential components, foundational concepts, and crucial skills required to master React JS in this comprehensive guide
- array objects destructuring import and export
- map filter arrow fncs (implicit return) spread operator
- Copy array using spread operator
let arr = [1, 2, 3, 4];
// real copy
let arr2 = [...arr];
arr.pop();
console.log(arr, arr2);
// object copy
let state = { name: "lucky", age: 23 };
let stateCopy = { ...state };
state.name = "HArsh";
console.log(state, stateCopy);
- Object Destructuring
let obj = { name: "lucky", age: 23 };
let { name, age } = obj;
console.log(name);
console.log(age);
- Array Destructuring
let arr = [12, function () {}];
let [first, sec] = arr;
console.log(first);
console.log(sec);
- import export
- hum log component banaate hai, component matlab page ka hissaa
- navbar sidebar cart home landing page second page, ab dikkat yeh aati hai har hissa alag alag component hai aur components ko hum log alag alag files mein rakhte hai, to inko last mein jodna bhi padta hai, jodne ke liyein use hota hai import & export
- navbar - export
- sidebar - export
- cart - import navbar sidebar
- main - import navbar
function Cart() {}
export default Cart;
export function Cart(){
}
import Cart from "./script";
import { Cart } from ".script.js";
- arrow functions
let sum = (a, b) => a + b;
console.log(sum(10, 12));
- impicit return
let value = val=>val+10;
console.log(value(20));
- map filter
- dono hi array pe chlte hai, aur dono kaa kaam hai array par kuchh perform krna hand "ek naya array return karna"
let arr = [1, 2, 3, 4, 5];
- map - har element par kuch karo aur naye array mein rakho
let arr2 = arr.map((item) => item * 10);
console.log(arr2);
let state = [11, 22, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 14];
let greaterFive = state.map((elem) => (elem > 5 ? elem + 5 : elem));
console.log(greaterFive);
- map filter mein ek hi farak hai, map saare bande lautata hai matlab ki count kam nahi hoga, filter bando ko kam kar skta hai
- ek array mein sabhi nums jo ki 5 se bade hai unmein 10 add kro
- jab originl array ka size kam naa hona ho waha map use hota hai
- jab original array ka size kam krna ho toh wha filter use hota hai
- ek array mein se saare wo nums hata do jo ki 5 se chhote hai
- filter
let arr = [1, 2, 3, 4, 5, 6];
let filterArr = arr.filter((elem) => elem > 5);
console.log(filterArr);

Extensions:
- tabnine
- prettier
Download :
- node js
- use vite vs create react app
npm create vite@latest
vite project : setup
cd setup
npm i
npm run dev
#### Understanding JSX
- jsx -> jsx is actually a very similar looking structure like HTMl but with super powers
- jsx sirf dikhta hai HTML ki trah par hota nhi
- It converted into React.createElement
- jsx is very similar to HTML but with superpowers
- conversion to javascript
{login ? 'profile':'login'}
Hey {2 + 2}
// output Hey 4

- Creating Card Component
### Section 3: Reusable Components
- Use Array map method.
const data = ["ajay", "rahul", "sachin", "udesh"];
{data.map((item, index) => (
{item}
))}
- Showing Card With Data
- Create Array of data
const data = [
{
image:'',
name:'',
desc:''
}
]
- and use map method to use different data with card.
#### React Fragments
- unnecessary div creation stop
- Enclosed all elements in one wrapper without creating div or other element use React Fragment
<>
>
### Section 4: Conditional Rendering
- Instock Check
{item.inStock ? "InStock" : "Out Of Stock"}
- Handling Events:
console.log("download song")}
>
Download Now
// seperatae function
const handleClick = () => {
console.log("mouse over event");
};
### Section 5: Managing State and Understanding the State Hook
- state variable takes care of react updation
- It will take care of react changes
- state ek data hota hai, react is data ka khayaal rkhta hai, jab bhi ye data change hota hai react page ko update karta hai
- state koi bhi data ho skta hai, jaise ki score = 0
const [score,setScore] = useState(0);
// onClick par apply krdo
const handleScore = () => {
setScore(score + 1);
};
- Based on Previous Value
onClick={() => setVal((prev) => prev + 1)}
- Use object data in useState
const [data,setData] = useState({name:'Lucky',isBanned:false});
onClick={() => setData({ name: "Divyanshu", isBanned: true })}
onClick={() => setData({ ...data, isBanned: !data.isBanned })}
#### Section 6 : Mastering the useState() hook
- useState not update synchronously
- add object property to useState
- useState state ko turant update nahi karta, wo useState state ko update karta hai apne hisaab se function completion ke baad to fix performance issue
const [val, setVal] = useState({ name: "lucky",age: 23 });
Name : {val.name}
Age : {val.age}
Role : {val.gender}
{setVal({ ...val, gender: "Male" })
console.log(val);
}
}
>
Click
- Use Array in useState
{val.map((item, index) => (
{item}
))}
setVal(() => val.filter((item, index) => index != 2))}
// onClick={() =>
// setVal(() => {
// return val.filter((item, index) => index != val.length - 1);
// })
// }
className="px-3 py-1 text-md bg-blue-500 rounded-full text-white"
>
Change
- Remove even values from an Array
onClick={() =>
setVal(() => val.filter((item, index) => item % 2 !== 0))
}
- Arrays Addition
onClick={() => setVal([...val, 10])}
- Change array of an object
const [val, setVal] = useState([
{ name: "lucky", age: 23 },
{ name: "Shivam", age: 34 },
{ name: "golu", age: 25 },
]);
onClick={() =>
setVal(() =>
val.map((item, index) =>
item.name === "Shivam" ? { name: "Shivam", age: 55 } : item
)
)
}
#### Section 7 : useState() Hooks
- Solve small-small questions
- print bahar jaao if val is false and print mat jao iv val is true
{data === false ? "BAHAR JAO" : "MAT JAO"}
- Use React icons
npm i react-icons --save
- switch Images:
setVal(() => !val)}
className="w-10 h-10 bg-[#dadada8b] flex items-center justify-center rounded-full absolute bottom-[0%] left-1/2 -translate-x-[50%] -translate-y-[50%]"
>
#### Section 8 : Passing Data via Props
- Pass Data via prop
- props use hote hai aapke components ko reuable bnane ke liyein consider karo aapke pass ek button hai and aapko us button ko alag alag jagah daalna hai app mein, to aap ek button ek mein baaneyin aur uska data hard coded karne ki jagah parent component se send karde and child component par use kar le
{btn}
- Array of object change via props functions
const handleFriendsBtn = (index) => {
setRealData((prev) => {
return prev.map((item, ind) => {
if (ind === index) {
return { ...item, friends: !item.friends };
}
return item;
});
});
};
- Dynamic class change
handleFriendsBtn(index)}
className={`px-3 mt-4 py-1 text-sm text-white ${
friends ? "bg-green-600" : "bg-blue-500"
} font-semibold rounded-md`}
>
{friends ? "Add Friend" : "Friend"}
{/* {friends ? "ADD FRIEND" : "Friends"} */}
#### Section 9 : Props and State Exercise
- Create card add build feature Add To favourites
const [song, setSong] = useState(data);
const [favouritesCount, setFavouritesCount] = useState(0);
const handleFavourites = (index) => {
setSong((prev) => {
return prev.map((item, indx) => {
if (indx === index) {
return { ...item, favourites: !item.favourites };
}
return item;
});
});
setFavouritesCount((prev) => prev + 1);
};
{song.map((item, indx) => (
))}
##### React Styled Componnets
- CSS Modules - jismein aap kabhi kisi website ka code dekhte ho aur wha par aapko css classes ka naam bada aada teda dikhta hai
- UI library- tailwind css, material UI,bootstrap,Chakra UI
- create file style.module.css
.a{
color:'red';
}
#### Section : 10 Form Handling
- Form Handling
- form basic nature or we can say default nature is to get submmitted but react says no page reload
- website submit ho jaati hai form submit krne par.
- How react handle things in Form
- React prevents Form Submission
- use Ref - is trike mein hum har input ko select kar lete hai and unki value tab nikaalte hai jab form submit hota hai
- use ref ke through html input ko select kar skte hai
const name = useRef(null);
const password = useRef(null);
const handleSubmit = (e) => {
e.preventDefault();
console.log(name.current.value,
password.current.value);
};
- controlled components
const [username, setName] = useState({ name: "", age: "" });
const handleSubmit = (e) => {
e.preventDefault();
console.log(username);
};
setName({ ...username, name: e.target.value })}
/>
setName({ ...username, age: e.target.value })}
/>
- react hook form
- install react-form-hook package
npm i react-hook-form
import React from "react";
import { useForm } from "react-hook-form";
const ReactForm = () => {
const { register, handleSubmit } = useForm();
// console.log(register());
return (
console.log(data))}>
{" "}
{" "}
{" "}
{" "}
{" "}
{" "}
);
};
export default ReactForm;
#### Section 11 : Form Handling Exercise
- Form Handle Exercise
- App - Cards - Card - Form
- Add form Data into Card component
const [users, setUsers] = useState([]);
const addFormData = (data) => {
setUsers([...users, data]);
};
- Reset Input Values
// provided by react-hook-form
reset()
- Remove Elements From Card
const handleRemove = (id) => {
setUsers(() => users.filter((item, index) => index != id));
};
#### Section 12 : React JS Routing and Beyond
- Configure react router to use react-routing
- React Uses single page approach in application i.e. no page reload after page changes, for this we use react routing.
- To move From one Page to another without reloading the website, so that website is called Web Application (for not reloading whole page).
npm i react-router-dom
- Wrap Main Container main.jsx
- Create Navbar
Home
User
Home
services
// Implement Routing
} />
} />
} />
} />
- Use navigate hook for back to particular route
const navigate = useNavigate();
const back = () => {
navigate("/");
// console.log("hey");
};
- Use NavLink to active & de-Activate class
{
console.log(e);
}}
to="/"
>
Home
- Change color three ways :
- through style
style={(e) => {
return { color: e.isActive ? "tomato" : "" };
}}
- Through className :
{
return [
e.isActive ? "text-red-300" : "",
e.isActive ? "font-semibold text-xl" : "",
].join(" ");
}}
to="/about"
>
About
- Inside Child Component
{(e) => {
return (
User
);
}}
{/* User */}
### Section 14 : How to integrate API in REACT JS
- The concept for connecting frontEnd With Backend is called AJAX (Asynchronous JavaScript XML) & which implements this communication is through fetch/axois.
- API is an communication medium to build relation
- API allow the communication with each other using requests and responses.
- Using FETCH/AXIOS Method we can access third party API.
- Connect frontEnd with Backend through an API
import axios from "axios";
import "./App.css";
import { useState } from "react";
function App() {
const [products, setProducts] = useState([]);
const getProducts = () => {
const api = "https://fakestoreapi.com/products";
axios
.get(api)
.then((products) => {
// console.log(products);
setProducts(products.data);
})
.catch((err) => console.log(err.message));
};
const addProducts = () => {
const api = "https://fakestoreapi.com/products";
axios
.post(api, {
title: "test product",
price: 13.5,
description: "lorem ipsum set",
image: "https://i.pravatar.cc",
category: "electronic",
})
.then((products) => {
console.log(products);
})
.catch((err) => console.log(err.message));
};
return (
App
Get Products
Add Products
{products.length > 0
? products.map((item, index) => (
-
Product Name: {item.title}
))
: "Loading....!!"}
);
}
export default App;
- LifeCycle Method name useEffect in functional Component:(Three Types of LifeCycle Methods)
- Component Mounting - creation
- Component Updating - updation (when useState is Changed or changes in view)
- Component UnMounting - deletion/destroy
- Component Creation
useEffect(()=>{
console.log('Component Creation');
return ()=>{
console.log('Component Deletion From DOM');
}
})
useEffect(() => {
console.log("SErvices Run");
return () => {
console.log("SErvice Destroyed");
};
});
#### Section 15 : useEffect() on State Change
- Hook - useEffect() on state change
- Refresh : Component Deletion + Component Updation
- Update : Component Deletion + Component Creation
const [first, setFirst] = useState("This is normal data");
const [second, setSecond] = useState("This is very Large Data");
useEffect(() => {
console.log("SErvices Run");
return () => {
console.log("SErvice Destroyed");
};
}, [second]);
- Call API When component is loaded using useEffect HOOk we call it.
useEffect(() => {
const api = "https://fakestoreapi.com/products";
axios
.get(api)
.then((products) => {
// console.log(products);
setProducts(products.data);
})
.catch((err) => console.log(err.message));
}, []);
- OutSourcing the Code
- writing import axois from 'axios' causes sometimes problem & write this line in 10 20 30 40 .. components is lengthy & create issue for Us
- While requesting to the API - the Header information, cookies,authorization,token, many things generated & for this we have to take of this to not to call an API when other component is added
- Login - profile, timeline , chats enabled
- Call one time & reference call everytime (create one time object).
- Not call axios everytime.
import axios from "axios";
// export { axios };
const instance = axios.create({
baseURL: "https://fakestoreapi.com",
});
axios
.get("/users")
.then((users) => {
console.log(users);
// setProducts(users.address);
})
.catch((err) => console.log(err.message));
export default instance;
#### Section 16 : React Context API
- It solves Prop Drilling Problem
- Prop Drilling means sharing data between one component to another & another to another means parent to child to son
- From Parent to Child Data Pass only .
- Wrap Application via context
- create context & create UserContext
import React, { createContext, useState } from "react";
export const UserContext = createContext();
const Context = (props) => {
// console.log(props);
const [users, setUser] = useState([
{
id: 0,
username: "John Doe",
city: "USA",
},
{
id: 1,
username: "Lucky",
city: "Delhi",
},
{
id: 2,
username: "Harsh",
city: "Bhopal",
},
]);
return (
<>
{props.children}
>
);
};
export default Context;
- use data via components
const { users, setUser } = useContext(UserContext);
- use navigate hook for go back
const navigate= useNavigate();
// apply on go back button
const handleBack =()=>{
navigate('/user');
}

#### GSAP X Reactjs
##### Introduction and Setup: GSAP X React.js for Stunning Animations
- Install neccessary packages
npm i gsap
npm i @gsap/react
- Two ways to create GSAP Animation
- useRef()
- useGSAP(()=>{
gsap.to(selector,{}) })
- using useRef:
const boxRef = useRef();
useGSAP(() => {
gsap.to(boxRef.current, {
x: 600,
y: 200,
});
});
- Using normal useGSAP & pass selector
useGSAP(() => {
gsap.to(".box", {
x: 1000,
delay: 1,
duration: 2,
rotate: 360,
backgroundColor: "blue",
});
});
##### IMAGE PREVIEW:
##### GSAP Timeline: Animate Like a Pro
- define timeline
const tl = gsap.timeline();
useGSAP(() => {
tl.to(boxRef.current, {
x: 1200,
rotate: 360,
borderRadius: "50%",
duration: 2,
delay: 1,
});
tl.to(circleRef.current, {
x: 1200,
rotate: 360,
borderRadius: "10px",
duration: 2,
});
});
useGSAP(
() => {
gsap.to(".box", {
rotate: 360,
duration: 1.5,
delay: 1,
});
},
{ scope: ".container1" }
);
