For how long? That’s the crux of the question. If you don’t know what you’re doing and your code “is prob terrible” the app will break in unexpected ways which are hard to diagnose and fix. If you were a carpenter, would you be proud to sell a chair which held up the two or three times you’ve sat on it but which you can’t confidently say won’t break in six months when your client’s spouse is using it?
If you ever wonder why software today is terrible, that’s a big part of it: people throwing stuff at the wall until it kind of works instead of taking care to make it good and correct which isn’t that much extra effort.
You’re far from the only one doing things that way. And that’s a shame, because we’re all worse off for it.
