UI Frameworks are a bloated mess. I'm not singling any framework out. They're all like this. They all add bloat and dependencies and many files. That's why every few years they get deprecated. UI Frameworks are a result of thousands of developers with nothing to do but complicate an otherwise simple process. You don't need Javascript UI frameworks 99% of the time.
