JavaScript Iterators

for...of Loop

Modern way to iterate over arrays and strings.

```javascript const fruits = ['apple', 'banana', 'orange'];

for (const fruit of fruits) { console.log(fruit); } ```

**Better than:** Traditional for loop

Iterable Objects

Arrays, strings, maps, sets are iterable.

```javascript for (const char of 'hello') { console.log(char); } ```

Key Takeaway

for...of iterates over iterable objects. Cleaner than traditional loops. Works with arrays, strings, maps, sets.
