JavaScript Type Conversion

Explicit Conversion

Convert types manually:

```javascript String(123); // "123" Number("123"); // 123 Boolean(1); // true ```

Implicit Conversion (Coercion)

JavaScript converts automatically:

```javascript '5' + 3; // "53" (number to string) '5' - 3; // 2 (string to number) ```

Key Takeaway

Explicit conversion is clear. Implicit can be surprising. Understand coercion to avoid bugs.
