Bun, Deno, Node.js? Recreating a JavaScript runtime from Scratch - Erick Wendel - NDC Oslo 2023

Bun, Deno, and many other JavaScript runtimes have been hype, but do you know why? Is it that easy to make a runtime from scratch? I've been researching the secret behind Node.js' power and why there are so many new JavaScript runtimes coming up. Breaking down each key component used on Node.js I've come to interesting conclusions that many people used to say whereas in practice it works a bit differently. In this talk, attendees will learn the concepts used to create a new JavaScript runtime. They're going to go through an example of how to make a JavaScript runtime by following what's behind the scenes on the Node.js project using C++. They'll learn the relationship between Chrome's V8 and Libuv and what makes one JavaScript runtime better than others. This talk will cover the following topics: - What's a JavaScript Engine - V8 - Why Node.js uses Libuv - How to create a JS Runtime from scratch Check out our new channel: NDC Clips: @ndcclips Check out more of our featured speakers and talks at https://ndcconferences.com/ https://ndcoslo.com/
