Adding keyword replacements for Javascript built-in library methods

[zainimran]

I am planning to use this amazing transpiler to teach coding to a group of urdu-literate students. While exploring, I was thinking this transpiler should also support urdu replacements for the popular built-in Javascript functions as well. I am talking about String.length, Array.push etc. Anyone here who can add such support or if not could guide me how to use this repo so that I can try adding it myself. Thank you
