📖 About the talk To many JavaScript developers, JavaScript engines seem like black magic. But they really aren't! They're just programs, like anything else, and you too can understand at a high level how they work, and even contribute. Let me demystify Hermes, and explain to you how its pieces — bytecode, interpreter, garbage collector, hidden classes, and more — all fit together to run your React Native app. We'll also take a look at Hermes's C++ codebase, and make a few changes, and compile it! 🗣 Speaker Bio CTO at Nozbe.
