HUD Codeblock Script Request

I used to refer to AI to help me build my codeblock scripts and it would get me within 85-90% of completion with me doing minor things to make it work, however, with the influx of Typescript resources, none of my AI sources give me what I need in codeblocks anymore, now it is all in typescript - which I do not know at all, and do not have the proper javascript background to even begin to understand it.

With that being said, does anyone have a good old fashion codeblock script for a HUD health bar that updates when the player is injured and healed?
