Hermes V1 is here, but what does that really mean for React Native developers? In this live stream, Łukasz Chludziński and Szymon Chmal are joined by Matt Hargett to unpack the reality behind Hermes V1: what’s new, what’s changing, and what’s next.
They discuss how Hermes has evolved from a fast, lightweight JS engine for React Native into a more capable runtime with support for modern JavaScript features, better performance, and an experimental JIT compiler. You’ll hear practical insights on when JIT helps (and when it doesn’t), how Hermes handles real-world device constraints, and what to expect as work toward Static Hermes continues.
