> Like the author of this post, I appreciate Solid's API because component's only render (i.e. run) once by default and then you define which sections of the component should re-render on changes by using "signals" provided by the library (e.g. `createSignal()` and `createEffect()`). In react, the entire component re-renders on every change and you need to specify which code should _not_ re-run. This was necessary because of the way react was created, but strikes me as fundamentally flawed.

I don't particularly like React, but this strikes me as the one thing it got right; the only "always correct" thing to do is to rebuild the VDOM on any change, so that's the default.

Then you can be more selective about which parts as performance dictates.
