Convert to JavaScript

I would need help in converting converting pseudocode to JavaScript. I already have the pseudocode in a html file but need it to be converted to JavaScript and run like it should. I would need to do this for two assignments, which I will leave below, in different zip files so they can be done separately with their own instructions.

I believe the pseudocode used in the html files is in the correct spot/area however if they are not you are free to change and move them where they should be.
