| Speeding Up the JavaScript Ecosystem: npm Scripts — The latest in what has been a fascinating series on finding ‘low hanging fruit’ when it comes to performance in the JavaScript world. The author explains it best himself: “‘npm scripts’ are executed by JavaScript developers … all the time. Despite their high usage they are not particularly well optimized and add about 400ms of overhead. In this article we were able to bring that down to ~22ms.” What Marvin does here is a valuable skill for all developers to pick up, and you can enjoy more by going back to the start.

| IN BRIEF: GitHub had to update its RSA SSH host key today so you may see security related warnings when pushing and cloning. It's easy to fix, but check the new fingerprint matches – it's for your own security. The New Stack caught up with Svelte's Rich Harris on SvelteKit and what's coming for Svelte 4. The React team shared some cutting edge updates on what they're working on including React Server Components and an optimizing compiler. If you were experiencing errors on the official Node site last week, here's the (detailed) post mortem of why. Config errors and inappropriate caching, mostly. ✨ Did you know there's a market in fake GitHub stars? Some developers analyzed some repos to learn more about it. 🥇 Congratulations to Lea Verou on her TC39 appointment. Her efforts to push the Web forward are legendary.
