ECMAScript excitement 😉

Congrats to @chronicles.org on advancing the Enum proposal to Stage 1 at TC39 today 🎉

This aims to bring the good parts of TypeScript enums to JavaScript plus enhancements such as new datatypes & potentially runtime performance improvements 👍

It’s more important than ever for Europe to fund strategic open source projects for open, decentralized communication systems (like Matrix) and application platforms/the open web (like Servo). We all need to be in control of our own computers, and it makes sense to fund as defense spending.

"erasableSyntaxOnly" was the result of an open collaboration between Node folk & the TypeScript team, started by @satanacchio.bsky.social 🙏

Thanks to @searyanc.dev for implementing this feature 👍

@mattpocock.com's excellent explainer article is here:

www.totaltypescript.com/erasable-syn...

TypeScript 5.8 Ships --erasableSyntaxOnly To Disable Enums

TypeScript 5.8's new erasableSyntaxOnly flag enforces pure type annotations by disabling enums, namespaces, and parameter properties.
