Adding a Byte to a Hexadecimal Escape Sequence in JavaScript: A Step-by-Step Guide

I am currently facing an issue with JavaScript and due to my limited expertise in this area, I am seeking assistance.

The challenge at hand involves hashing a "string" of bytes, where I need to add another byte that is generated within a script. Adding this byte all at once using '+ '\x25'' is not feasible as I must add the digits individually. However, when I concatenate the new byte, it is interpreted as four characters instead of one - '\', 'x', '2', '5' instead of '%'. Is there a way to add the byte without it being translated into ASCII?

Check out this solution:

let firstDigit = 2;
let secondDigit = 5;
let number = `${firstDigit}${secondDigit}`;

let charToAdd = String.fromCharCode(Number.parseInt(number, 16));

console.log(charToAdd);
