Advanced JavaScript

Course Overview

This course is designed for developers who have a solid grasp of fundamental JavaScript. We'll explore complex asynchronous patterns, advanced object-oriented techniques, performance optimizations, and modern module systems. Prepare to elevate your JavaScript skills to an expert level.

Key Modules

Promises & Beyond

Understand the nuances of asynchronous operations, including Promise chaining, error handling, and concurrency.

`Promise` constructor
`then`, `catch`, `finally`
`Promise.all`, `Promise.race`, `Promise.any`

Async/Await Mastery

Write cleaner, more readable asynchronous code with the async/await syntax, and handle errors effectively.

`async` functions
`await` keyword
Error handling with `try...catch`
Top-level await

Prototypes & Inheritance

Unlock the power of JavaScript's prototypal inheritance model and understand constructor functions.

Prototypal chain
`__proto__` vs. `prototype`
`Object.create()`
Constructor functions

Module Systems

Explore ES Modules and CommonJS, understanding how to organize, import, and export code efficiently.

ES Modules (`import`/`export`)
CommonJS (`require`/`module.exports`)
Dynamic imports

Performance Optimization

Learn techniques to write performant JavaScript, including memory management, efficient DOM manipulation, and code splitting.
