JavaScript Type Conversion

Explicit Conversion

Convert types manually:

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

Implicit Conversion (Coercion)

JavaScript converts automatically:

'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.
