## Javascript /typeScript Interview Questions

1. Asynchronous JavaScript:

  - Promises: Understand how to handle asynchronous operations gracefully.

Async/Await: Learn this modern approach to asynchronous code which makes your asynchronous code look more like traditional synchronous code.

Callbacks: Fundamental for asynchronous programming, though less preferred now due to "callback hell".

2. Functional Programming Concepts:

  - First-Class Functions: Understanding that functions can be assigned to variables, passed as arguments, and returned from other functions.

Higher-Order Functions: Functions that take other functions as arguments or return functions.

Pure Functions, Side Effects, and State Mutation: Concepts essential for writing clean, maintainable, and predictable code.

Closures: Understanding how an inner function has access to the outer function’s variables and the implications of this.

3. Advanced Techniques and Concepts:

   - Currying and Partial Application: Techniques for working with functions and improving code reusability.

Memoization: Optimization technique to speed up function execution by storing results of expensive function calls.

Prototypal Inheritance: Understanding the prototype chain, and how objects inherit properties and methods.

Design Patterns: Learning patterns like Module, Singleton, Observer, Factory, etc., for solving common design problems.

4. Error Handling and Debugging:

   - Exception handling with try...catch.

   - Understanding and using JavaScript's debugging tools.

5. Advanced DOM Manipulation:

  - Event Bubbling and Capturing: Understanding how events propagate through the DOM.

  - Document Fragments and performance considerations when interacting with the DOM.

  - Custom Events: Creating and dispatching custom event types.

6. ES6 and Beyond Features:

  - Understanding the latest ECMAScript features such as arrow functions, template literals, spread/rest operators, destructuring, ES6 modules, and more.

7. Browser APIs and Web Technologies:

  - WebSockets for real-time communication.

Service Workers for offline capabilities and background tasks.

WebRTC for peer-to-peer communication.
