JavaScript Advanced Tips 🚀

Here are some essential advanced JavaScript techniques to enhance your coding skills:

1. Scope & Closures 🌍

• Lexical Scoping: JavaScript uses lexical scoping, meaning functions are scoped to the block in which they're defined.
• Closure Example:

  function createCounter() {
    let count = 0;
    return () => count++;
  }

2. Arrow Functions ➡️

• Concise Syntax: Use arrow functions for shorter code.

  const add = (a, b) => a + b;
  

• No Own this: Arrow functions inherit this from the parent scope.

3. Modularization 📦

• ES Modules: Leverage import/export for clean code structure.
• IIFE (Immediately Invoked Function Expression):

  (function() { /* module code */ })();
  

4. Performance Optimization ⚡

• Memoization: Cache results of expensive function calls.
• Avoid Unnecessary DOM Manipulation: Batch updates to improve rendering efficiency.

5. Advanced Data Structures 🧠

• Map & Set: Use Map for key-value pairs and Set for unique collections.
• Proxy: Create dynamic objects with Proxy for enhanced control.
