String() — convert number to string

📖 Usage Example

String(42)         // → '42'
String(true)       // → 'true'
String(null)       // → 'null'
String(undefined)  // → 'undefined'

Use String() to safely convert any value to its string representation.

String Constructor

String(value) converts any value to its string representation without new.

Challenge: Implement numToString(n) that uses String(n) to convert a number to a string.

numToString(42)   // → '42'
numToString(3.14) // → '3.14'
