JS Practice — Built-in Objects

String.fromCharCode() — build a word

📖 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() — Multiple Codes

Pass multiple code values to build a string in one call.

Challenge: Implement buildWord(codes) that converts an array of char codes to a string.

buildWord([72, 105]) // → 'Hi'
