String.fromCharCode() — uppercase alphabet range

📖 Usage Example

String.fromCharCode(65)        // → 'A'
String.fromCharCode(97)        // → 'a'
String.fromCharCode(72, 105)   // → 'Hi'

Use String.fromCharCode() to create a string from one or more UTF-16 char code values.

String.fromCharCode() — ASCII Range

The uppercase letters A–Z are codes 65–90.

Challenge: Implement getUppercaseLetter(n) that returns the nth uppercase letter (0-indexed, so 0 → 'A', 25 → 'Z').

getUppercaseLetter(0)  // → 'A'
getUppercaseLetter(25) // → 'Z'
