How to convert string to byte array in TypeScript

Answer 1

const str: string = "TypeScript";

// Convert string to byte array
const encoder: TextEncoder = new TextEncoder();
const byteArray: Uint8Array<ArrayBufferLike> = encoder.encode(str);

console.log(byteArray);

const byteArray_length: number = byteArray.length;
for (let i = 0; i < byteArray_length; i++) {
    console.log(byteArray[i]);
}
