First Impressions Using React Native
I think it's a very strong point that moving script code off the main thread can help achieve smooth UIs. No more GC pauses, no more slowdowns if the JS engine hits a snag, etc.I think this is actually possible on the web as well. Someone could write a UI framework which runs JS in a Worker, and sends messages to the main thread, on which there is HTML and minimal JS to receive the messages and handle them.I'm surprised this hasn't been done, or has it and I just haven't heard about it?If you're worried about the overhead of transferring lots of messages from the Worker to the main thread, I think it can be pretty fast actually. I did an experiment with proxying WebGL that way, which is a fairly high-traffic API, with nice results,https://blog.mozilla.org/research/2014/07/22/webgl-in-web-wo...For something rendering a UI, message passing overhead should be reasonable, especially if the framework is smart enough to only send over what changes (like React Native does).
