cheatsheet - javascript / cheasheet - Arrays and Strings / cheatsheet DOM

Hi to you all.

First of all, thanks a lot to Jad Joubran for developing this course to learn Javascript. I really learn a lot here and I enjoy how the course and the challengies are made :).
Concerning my Issue, I would like to avoid having to remember all the methods I learn on learnjavascriptonline.com and I would like to know if someone could advise me a ressource (or some ressources) to get the cheatsheets (with description of the methods if possible) I need for the web development with Javascript. It would be so useful for me to save time when I develop projects when I have the best cheatsheet.

Thanks in advance

The issue mentions JavaScript arrays, strings, and the DOM, but names no files, tests, or entry points. First clarify whether the desired outcome is new cheatsheet content, links to external resources, or changes to the course, then define the covered methods and what completion would include.
