From Scratch Web Games: A Beginners Guide to Game Development using HTML, CSS, and JavaScript
Chapter 4.1: JavaScript Basics Cheat Sheet
JavaScript is the programming language that is a standard part of browsers. While there have been several attempts of having additional languages, most attempts have failed. One arguable exception to this is TypeScript, which has a large following but unfortunately requires compiling into JavaScript before it can be used.
The purpose of the cheat sheet is to give you a summary of the main aspects of the JavaScript language, with classes and asynchronous work being in separate cheat sheets. If you fully understand what is in the cheat cheat then feel free to skim or skip this chapter. I urge those readers to attempt the project just to make sure they really do understand the material but that is up to you.
The cheat sheet is here and the source in my github repository located at https://github.com/BillySpelchan/FromScratchHTML_CSS_JS.
