A roundup of some other interesting stories in the broader JavaScript landscape, in case you’ve missed them:

-
ESLint v9.35.0 has been released with a new rule (
preserve-caught-error) for disallowing the loss of an originally caught error when re-throwing custom errors. -
Cloudflare has brought initial Node.js HTTP server support to Cloudflare Workers, its edge function platform.

Andromeda is the newest JavaScript runtime on the block, powered by the Nova engine. It’s built in Rust and boasts direct GPU accelerated graphics support, single file compilation, and memory safety.
-
Ripple is an interesting new TypeScript UI framework aiming to bring “the best parts of React, Solid and Svelte” to one package.
