React Native: Under the Hood

on YouTube ↗26m

" summary

Explains that React Native runs the React runtime on a JavaScriptCore runtime and communicates with platform code via an asynchronous serialized bridge that batches calls into a single message queue. Describes native primitives, a responder system for touches, a UIManager that schedules work on the main thread, a layout engine written in JS (transpilable to C/Java), remote debugging over WebSockets, a streaming demo with JS on a server, and claims it sustains 60 FPS in practice.
