this page is existing permalink for the following question:

What programming languages/tools did you use to make Elemental 4? I wanna know because I want to make something like that and don't know where to begin. The only programming language I know how to code in is Python.

you can peek how badly it's made here, but it's written in typescript with visual studio code, and uses a slightly custom and slightly outdated webpack setup. whatever works.

real trick is to not begin with a thing as complex as elemental 4. if you're asking where to begin, i cannot say how well you'll be if you try something really complex. but web dev doesnt have to be complex, so i wouldn't tell you to not try javascript and all.
