👀 The Three Pillars of JavaScript Bloat
Three reasons your node_modules is huge: needless ES3-era compat packages, micro-libraries with a single consumer, and ponyfills for APIs that shipped years ago! James, known for the e18e ecosystem performance project, offers some ways to calm the chaos.

🥶 Announcing TypeScript 6.0
Over six months in the making, TypeScript 6.0 is designed to bridge the gap between its self-hosted compiler and the (almost ready) Go-powered native compiler of TypeScript 7.0 .
There are new features (Temporal improvements, RegExp.escape, and more), but most important are the changes to help you prepare for 7.0:
• Numerous default changes: strict is now true, module is esnext, rootDir defaults to ., and more.
• A change that will affect many apps is types defaulting to [] rather than pulling in everything from node_modules/@types.
• Numerous deprecations: the es5 target, emitting AMD, UMD, and SystemJS modules, --baseUrl, and others.
• --stableTypeOrdering makes 6.0's type ordering behavior match 7.0's to help diagnose inference differences as you update.
