Standardizing JavaScript Decorators in TC39

Daniel Ehrenberg ยท Full Stack Fest 2019

JavaScript decorators were created in 2014 as a collaboration among the JavaScript ecosystem, and you've been able to use them in TypeScript and Babel. But they didn't make it into the JavaScript standard yet: not ES6, or any of the later versions, so far. We're working on standardizing decorators in TC39, the JavaScript standards committee, but some changes are required from the initial version.

In this talk, Daniel will explain what TC39 is and how we work. We'll look at some newer language feature proposals, such as Temporal and immutable records and tuples, and follow how decorators have been proceeding through the TC39 process, including why and how they're changing. TC39 could use your help in moving JavaScript forward.
