It was just for the challenge, please don't ever write such code :D
That sounds fun, I might try it. Thanks!
Do Electron apps count? I am amazed by editors like Atom and Visual Studio Code. They are packed with so many features and you basically can't tell them apart from native apps.
Do you dislike Bootstrap specifically or frameworks in general?
I like frameworks like Bootstrap because they make it easier to work in a team. Understanding other people's code is much easier when everyone uses the same standards and components.
It's just a trend thing in my opinion. There are some differences between the two but really nothing too important. Use whatever feels comfortable - it's only a package manager.
