But thanks for answering honestly.
There's new languages where it's a bit of an open question still where they lie on the spectrum. Go would be one of them. I'd guess somewhere between Python and Java. Javascript I would argue is between perl and python. And Rust ... well ... good question.
An office suite is a gigantic application, which will need feature upon feature upon feature upon feature. If you want it working on the web, I'd propose something like C++ and WASM.
Edit: also appears to be based in the eu, how fitting for this thread.
