String.fromCodePoint() — basic usage

📖 Usage Example

String.fromCodePoint(65)       // → 'A'
String.fromCodePoint(9731)     // → '☃'
String.fromCodePoint(128512)   // → '😀'

Use String.fromCodePoint() to create a string from Unicode code point values, including characters outside the BMP.

String.fromCodePoint()

String.fromCodePoint(...codePoints) returns a string from Unicode code point values. Unlike fromCharCode, it handles the full Unicode range including supplementary characters.

Challenge: Implement charFromCodePoint(cp) that returns the character for the given code point.

charFromCodePoint(65) // → 'A'
charFromCodePoint(9731) // → '☃'

💡 Hints (1)

• `String.fromCodePoint` accepts the same values as `String.fromCharCode` for BMP characters.
