I also learned javaScript by looking at other peoples’ projects. I also learned by placing block code, switching to javaScript, and seeing what it became. Many of my recent projects are in javaScript, and you can look at those if you want, though I don’t really write the most readable code. Feel free to ask any questions you have! Make sure to @ me though, so that I get a notification, otherwise I might never know you asked!
