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!

Hi. We will present an experimental IDE for navigating the ECMAScript specification document. The IDE provides a custom pseudocode notation that matches the look-and-feel of the ECMA-262 spec, and supports the usual features (outline view, go to definition, find usages, diff). We'll also demo functionality for advanced navigation and comprehension of pseudocode, such as pattern-based code search within the spec's algorithms, and local refactoring/modifying/annotating the spec for learning purposes.

Depression, dark thoughts, anxiety – These are some of the words that most of us would like to add to our ignore file. Discussing mental health is still taboo in our society, and it’s even more so in the developer ecosystem, where we pride ourselves on working long hours and our lack of sleep.

More than ever, we need to talk about mental health! This is why I want to share my experience with depression, general anxiety, ADHD, and experience volunteering at a suicide prevention hotline. Along with my thoughts on how we can improve the situation, I’ll be sharing some tips to help people be more open about these topics and issues – more importantly, I want to touch on how those struggling can ask for help and assistance when needed.

An opinion and methodologies on how to modernize an outdated and unmaintained codebase while at the same time delivering features. We will also explore how AI can support modernizing a legacy codebase.

Next.js is a great framework - until you want to deploy it somewhere that isn't Vercel. vinext is a Vite plugin from Cloudflare that reimplements the Next.js API surface from scratch, so your existing app runs everywhere with a single command. In this talk, we'll look at why this exists, how Cloudflare built it in a week using AI, and how close to "drop-in replacement" it actually gets.
