Type Coercion

Type coercion is when a programming language automatically converts a value from one type to another (e.g., number to string).

Types

• Implicit: Done automatically by the language
• Explicit: Done manually by the developer (e.g., Number("42"))

Common in Weak Typing

• "5" + 1 → "51" (number coerced to string)
• "5" - 1 → 4 (string coerced to number)
