17: Hermes JS Engine Development with Marc

Every time we get to talk about an open-source project on our podcast, we couldn't be happier. This episode we have Marc to talk about Hermes, an open-source JavaScript engine, optimised for running React Native apps on Android. You can listen to Marc explain why it was necessary to build a JavaScript engine to support the needs of a particular framework and get a glimpse of the architecture and the design decisions behind it.
