Static Hermes - The Next Generation of Hermes

Explore the evolution of non-web JavaScript engines in this 26-minute conference talk from React Native EU 2023. Dive into Static Hermes, a groundbreaking development that allows optional compilation of type-annotated JavaScript into native code, delivering performance comparable to C/C++. Learn about its support for mixing native and interpreted code, both typed and untyped, and discover how 'unsafe' language extensions enable direct manipulation of native types and APIs. Understand how these advancements combine native-like power with JavaScript's flexibility and convenience, potentially reshaping React Native development and the future of JavaScript engines. Presented by Tzvetan Mikov, an expert previously involved with the Hermes JavaScript Engine and Bloomberg L.P., now working on a confidential project to accelerate JavaScript performance.
