Node won server-side JS by being first. Then the guy who built it got on stage and apologised for it. Then a 22-year-old rewrote it in a language most JS devs never heard of and claimed 3x the speed. Then Deno - after years of being ideologically pure - quietly added node_modules support and nobody talked about it.

This talk is the story of how we ended up with three competing JS runtimes, what each one is actually betting on, and why the ending isn't a winner - it's a boring standard that might matter more than all of them.

How many times did we read about JavaScript being a bad language, JavaScript being on its way out and that technology X would kill it. In this talk, we will take a look at the lessons learnt from attempts at killing JavaScript. We will start as early as the late 90s where the battle for web-domination was still open. Then we will travel through time to understand the current state of an hypothetical javascript-less web platform.

React Server Components (RSC) represent a powerful new paradigm for building fast, interactive web applications by allowing server-side rendering of components alongside client-side ones. While Next.js has emerged as a popular framework for leveraging RSC, it's not the only option.

In this talk, we'll explore how to integrate React Server Components into a custom application without relying on Next.js. You'll learn about the core concepts of RSC, the benefits of server-side rendering, and how to configure your own custom server environment to take full advantage of RSC in any React project. By the end, you'll walk away with a deep understanding of how React Server Components work independently of popular frameworks and how to apply them to improve performance and scalability in your applications.

TC39 is working on two proposals, import defer and export defer, whose goal is to allow developers to extract better performance from native ESM, both in the browser and on the server. Let's go together through how they work, and when and where you'll be able to use them!
