React is dead easy to create a component and get going with whatever you want to create. But as your application grows it is really difficult to test. The React testing library sounds good in principle, but once you have useEffects, hooks, the DOM, and every other side effect running interwoven with your component logic, it becomes difficult test. Obscenely difficult. I think there's some tradeoff operating here. I want a front end framework that makes it a little easier to test, happy to go through some more pain to write components.
