Maybe this can help you:
Are you looking for anything particular?
And I don’t know TypeScript syntax. So it’s not comfortable to use it for me.
If at all you have problem in understanding TypeScript code, you may at least use online transpiler like typescriptlang.org/play/index.html
Mostly does not mean equal/fully/exactly. Otherwise, about a large number of things you could say that this is the same thing.
But I will certainly try, when I will have time for this.
It’ll take you through the basics and then have you build a grocery list app - all in JS. Once you get the hang of the structure of the files and the MVVM way of working, your own JS skills should help you out. It would be worth knowing about the CommonJS standard if you haven’t worked with this before. It can (at least it was for me) be daunting getting it going initially but I found most of my problems came from installing all the dependencies than with the code.
Also StackOverflow and this forum are your friends - good luck! I’m still not an expert but I LOVE working with NativeScript - hope you do to!
If you check out StackOverflow under my Wittner username you’ll see some of the stuff I had problems with starting out - might help.
