### At the end of the project, the following topics are to be covered;
- API's
- [Github followers API](https://api.github.com/users)
- [newsAPI](https://newsapi.org/)
- HTML
- CSS
- Nested CSS
~~~css
.card {
& img {
transition: 0.5s;
}
& img:hover {
rotate: 10deg;
scale: 1.02;
}
& .btn {
transition: scale 0.2s;
}
& .btn:hover {
scale: 1.03;
}
}

- JS
- senkron programing
```
console.log("Hello")
alert("Blocked") //? Blocking
console.time("gecikme")
delay(4000) //? blocking code - senkron
console.timeEnd("gecikme")
console.log("hi")
```
- Asenkron (setTimeout()) programing
```
setTimeout(() => {
console.log("I am fine")
console.timeEnd("timer")
}, 1000)
setTimeout(() => {
console.log("Whats up?")
console.timeEnd("timer")
}, 1000)
console.log("start")
console.time("timer")
```
- Asenkron (setInterval, clearInterval) programing
```
/? setInterval periyodik zaman araligi oluşturmak icin kullanilabilir.
//? clearInterval yardımıyla surekli devam interval pasif hale getirilir.
let count = 0
const sec1 = setInterval(() => {
console.log(++count)
if (count > 9) {
clearInterval(sec1)
}
}, 1000)
```
- Callback Hell (nested ve birbirine bagli callback'ler)
```
setTimeout(() => {
console.log("john:Hi");
setTimeout(() => {
console.log("Sarah: Hello");
setTimeout(() => {
console.log("John: How Are you?");
setTimeout(() => {
console.log("Sarah:Fine and you?");
}, 1000);
}, 1000);
}, 1000);
}, 1000);
```
- Promise()
```
const networkReq = new Promise((resolve, reject) => {
const data = { a: 1, b: 2 };
const success = Math.floor(Math.random() * 5); //? (0,1,2,3,4)
if (success) {
console.log("Data fetched");
resolve(data);
} else {
reject("Ohh no there is network error");
}
});
networkReq
.then((response) => console.log(response))
.then(() => console.log("2. then"))
.catch((err) => document.write(err))
.finally(() => console.log("Her zaman calisir"));
```
- fetch API
```
let veri = "";
fetch("https://api.github.com/users")
.then((res) => {
//! Error handling
if (!res.ok) {
throw new Error("Something went wrong", res.status);
// console.log("Something went wrong")
} else {
return res.json();
}
})
.then((data) => {
// veri = data
// console.log(veri)
showUsers(data);
})
.catch((err) => {
console.log(err);
const usersDiv = document.getElementById("users");
usersDiv.innerHTML = `
${err}
`;
});
// console.log(veri)
const showUsers = (users) => {
console.log(users);
const usersDiv = document.getElementById("users");
users.forEach((user) => {
// console.log(user.login)
usersDiv.innerHTML += `
`;
});
};
```
- async-await
```
const getNews = async () => {
const API_KEY = "2108f1dba8114b89b4a326fc6f71a5a8";
const URL = `https://newsapi.org/v2/top-headlines?country=us&apiKey=${API_KEY}`;
try {
const res = await fetch(URL);
// console.log(res);
//?Error handling
if (!res.ok) {
throw new Error("News can not be fetched");
}
const data = await res.json();
renderNews(data.articles);
} catch (err) {
// console.log(error);
renderError(err);
}
};
const renderNews = (news) => {
const newsDiv = document.getElementById("news");
news.map((item) => {
const { title, content, url, urlToImage } = item; //? destructure
newsDiv.innerHTML += `
`;
});
};
const renderError = (err) => {
const newsDiv = document.getElementById("news");
newsDiv.innerHTML = `
${err}
`;
};
window.addEventListener("load", () => {
getNews();
});```
- DOM Manipulations
- innerHTML
- innerText
- textContent
- DOM Selectors
- Events
- click
- load
- Array Methods
- forEach() & map()
```
const showUsers = (users) => {
console.log(users);
const usersDiv = document.getElementById("users");
users.forEach((user) => {
// console.log(user.login)
usersDiv.innerHTML += `
`;
});
};
```
```
const renderNews = (news) => {
const newsDiv = document.getElementById("news");
news.map((item) => {
const { title, content, url, urlToImage } = item; //? destructure
newsDiv.innerHTML += `
`;
});
};
});
