TypeScript String.fromCharCode() Method

The fromCharCode() is an inbuilt TypeScript String method. It mainly changes Unicode code points within the Basic Multilingual Plane (BMP) into strings. Although it provides a method for dealing with characters through typing on a keyboard it has restrictions when it comes to characters, outside the BMP.

Syntax:

String.fromCharCode(...codePoints: number[]): string

Parameters:

• codePoints: One or more Unicode code points to be converted into characters.

Return Value:

A string that contains characters whose Unicode points were passed as an argument within the method.

Example 1: In this example here we are creating a string from unicode code point values.

Javascript

let codeUnits: number[] =
    [
        71, 101, 101, 107, 115, 70,
        111, 114, 71, 101, 101, 107, 115
    ];

let geeksString: string = String
    .fromCharCode(...codeUnits);
console.log(geeksString);

Output:

GeeksForGeeks

Example 2: In this example here we are creating a string from unicode code point values.

Javascript

let codeUnits: number[] =
    [
        74, 111, 104, 110, 68, 111, 101
    ];

let name: string =
    String.fromCharCode(...codeUnits);
console.log(name);

Output:
