JavaScript has evolved significantly over the years, and mastering advanced topics is essential for building robust web applications. Here's a breakdown of key areas:

1. ES6+ Features 📚

  • Arrow Functions => simplify callbacks and maintain lexical this
  • Template Literals with backticks allow multi-line strings and embedded expressions
  • Destructuring enables easy extraction of array/object properties
  • Classes provide a more structured approach to object-oriented programming
  • Promises and async/await revolutionize asynchronous code handling
ES6 Features

2. Advanced Data Structures 🧱

  • Map and Set offer flexible key-value storage solutions
  • WeakMap and WeakSet help manage memory with garbage collection
  • Proxy and Reflect enable meta-programming capabilities
  • Symbol creates unique object keys

3. Performance Optimization ⚡

  • Use Web Workers for background processing
  • Implement lazy loading with import() syntax
  • Optimize DOM manipulations with document fragments
  • Leverage tree shaking in module bundlers
Performance Optimization

4. Modern Development Patterns 🛠️

  • Modular Development with ES6 modules
  • Functional Programming principles
  • Reactive Programming using RxJS
  • Design Patterns like Observer and Strategy
