In this session, we’ll peak under the hood of the V8 engine, which is the key piece when it comes to parsing & compiling JavaScript, whether in our Chromium-based browsers, or NodeJS and Deno backend runtimes. What is a Just-In-Time compilation, how do V8’s parser Ignition and compiler Turbofan work together, and how understanding concepts like Speculative Optimization, Hidden Classes, and Function Inlining help us write blazing-fast JavaScript code, are only some of the questions we’re going to reveal. And all of that with live coding examples and performance metrics.
