JavaScript Arrow Functions

Arrow Function Syntax

Shorter way to write functions.

```javascript // Regular function function add(a, b) { return a + b; }

// Arrow function const add = (a, b) => a + b; ```

When to Use

**Use arrow functions for:** - Callbacks - Array methods - Short functions

**Don't use for:** - Methods (this binding issues) - Constructors

Key Takeaway

Arrow functions are shorter. No `this` binding. Use for callbacks and short functions. Modern JavaScript standard.
