The other day, I needed to quickly whip up an internal dashboard with some dynamic logic. Being somewhat lazy, I just imported jQuery and some additional scripts for it, one of the small CSS-only libraries for basic styling, put all of the custom code in a single JS file and that's it.

No toolchains. No build process. No learning about any particular way of doing state managing or rendering or what have you. Just some files and some code.

It was delightfully simple. For bigger projects I do think that the likes of Vue strike a nice balance between features and usability, but I've also seen a lot of messing around with toolchains and package versions (or even stuff like needing to migrate away from AngularJS), sometimes it's nice to avoid all of that when you don't need that complexity.
