From the comments that have mentioned the efficient programming languages, my guess is there’s a bunch of devs in here that never got past the “c++ is hard!” stage.
The first time I saw an office app launch in my browser, I was both impressed that they got excel to work in a browser and appalled that they wanted excel to work in a browser at the same time. And I’ll admit that it does perform well considering it’s running in a fucking browser, but I’ll still launch the native app any time I actually want to work with a file that’s opened in the browser.
Keep at it, eventually things will click and you might find yourself appreciating the compiler errors and type strictness. Perhaps you’ll even spend time getting rid of warnings even though it will let you run without doing that, because they indicate edge cases that might break your program in difficult to debug ways.
