I learned by switching code from blocks to JavaScript and seeing what was generated. Then I found out about Classes and I made a very early version of this extermination game with a bunch of little rats running around on the screen, and then I just never looked back.
Most important answer: I don’t touch blocks unless I’m helping someone else with block code or I’m testing out an extension I’ve made.
P.S. it’s actually “static typescript” and the full list of functionality is here
My favorite feature is the conditional operator ? : which I use a lot.
