Daniel Ehrenberg — The future of JavaScript modules: JS module blocks and native bundling

— —
ES6 added a built-in concept of modules to JavaScript in 2015, though uptake since then has been more gradual, it is the de-facto default for authoring new JS today. In this talk, Daniel will explain two new proposals in this space, making modules even more useful.

JS module blocks let you run a module in a Worker without splitting the code out into a separate file. This way, it's easier to run code in parallel or keep code reusable, even when bundlers are involved.
Resource bundles let browsers understand bundler output better, so they can implement ES module semantics natively and improve loading performance.
