Replacing each letter wich another letter
I am wondering how to replace each letter of a string with another letter. For example A -> D.
I have tried using .replace() (repeating it in each line for every letter) but when I replace the letter A with the letter D and then try to replace the letter D with the letter H it just replaces the letter A twice so instead of AD -> DH I end up with AD -> HH.
Im sure there is a better and simpler way of doing this.
Thank you in advance.

Build up a dictionary:
const dict = { A: "D", D: "A", /*...*/ };
Then split the string into an array, map that to a new array by applying the replacement and join the array back to a string:
const output = input.split("").map(char => dict[char]).join("");

You may also use thereplacemethod directly like so:input.replace(/./g, c => dict[c] || c).

You may also use thereplacemethod directly like so:input.replace(/./g, c => dict[c] || c).
