Hermes V1 is officially here, but what does that really mean for you? In this live session, Łukasz Chludziński, Matt Hargett, and Szymon Chmal will walk through what Hermes V1 includes, what it intentionally leaves out, and how it differs from engines like JSC and QuickJS (Lynx).

We’ll examine architecture-level tradeoffs, what “static Hermes” really refers to, and where the engine is headed next. You’ll hear directly from engineers who’ve worked around these systems and get a clear technical picture of where Hermes fits in the React Native ecosystem.
