Concurrent Renderer: Because Not Every Update Deserves a Front Row Seat
Concurrent Renderer gives React Native the power to pause, prioritize, and resume rendering work—so your app stays responsive even under pressure. Instead of blocking the UI for every update, React now handles what matters first. It’s like switching from a to-do list to triage.

Fabric is React Native’s new rendering engine that aligns closely with React’s internals. It brings synchronous layout, better performance, and tighter control over UI updates—making rendering faster, more predictable, and actually React-like. Think of it as tearing out the rickety scaffolding and rebuilding the UI pipeline with steel beams.

JSI (JavaScript Interface) is a low-level C++ layer in React Native’s New Architecture that enables synchronous, direct communication between JavaScript and native code—no JSON, no async bridge, no waiting. It unlocks runtime flexibility, faster performance, and native-level access for libraries like Reanimated, Skia, and Nitro. Think of it as the power cable React Native always needed but never had.
