In Solid, the component body is setup code. It runs a single time.

A memo is a read-only derived value.

const count = signal(0); const doubled = computed(() => count.value * 2);

So while Solid's JSX and might resemble React it by no means works like React and there should be no illusions that a JSX library will just work with Solid. Afterall, there are no JSX libraries, as they all work without JSX, only HyperScript or React ones.

Remember even though the syntax is almost identical, there are significant differences between how Solid's JSX works and a library like React.

Solid’s State primitive is arguably its most powerful and distinctive one. Through the use of proxies and explicit setters it gives the control of an immutable interface and the performance of a mutable one

The fun thing here is that SolidJs doesn’t uses virtual dom instead of that it uses fine-grained updates.

Solid supports most React features like Fragments, Portals, Context, Suspense, Error Boundaries, Lazy Components, Async Rendering, Implicit Event Delegation, SSR
