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.

The JavaScript ecosystem is longing for a standardized tooling. No more plumbing work, no more choice fatigue and no more analysis paralysis. But how would such a tool look like? Together, we have a look at the newly released Vite+ Alpha and see if the new open source CLI can hold up to its promises, covering developer's tooling needs and let them focus on shipping, especially in an agentic age.
