cellx VS reactively

Fine-grained reactivity libraries have been growing in popularity recently. Examples include new libraries like Preact Signals, µsignal, and now Reactively, as well as longer-standing libraries like Solid, S.js, and CellX. Using these libraries, programmers can make individual variables and functions reactive. Reactive functions run automatically, and re-run 'in reaction' to changes in their sources.

But what if the vertices change? What if the user changes the shape and number of the tiles while the video is playing? In that case, we will need to update the buffer. Reactively can handle that situation automatically. Reactively tracks dependencies and will re-execute the body of the getter if the dependencies change, vertexBuffer will create a new GPUBuffer as required. In this case, shapeVerts might change if the user changes the size and shape of the mosaic tiles in the control panel and then it would be appropriate to rebuild the GPUBuffer for new vertices for the next rendered frame.

Adding on to Ryan's comment, Reactively actually does have an object oriented syntax using typescript decorators that is built around the core library

Reactivity libraries are at the heart of modern web component frameworks like Solid, Qwik, Vue, and Svelte. And in some cases you can add fine-grained reactive state management to other libraries like Lit and React. Reactively comes with a decorator for adding reactive properties to any class, as well as prototype integration with Lit. Preact Signals comes with a prototype integration with React. Expect more integrations as these reactivity cores mature.
