A new React Handbook page that discusses two key aspects of React performance: Loading and Runtime Performance. Loading Performance focuses on how quickly a webpage's content loads. The handbook suggests optimization techniques like GZip compression, image optimization, and code splitting to improve loading performance. Runtime Performance, on the other hand, measures the application's smoothness post-load. The handbook recommends strategies such as fixing rendering issues, offloading work to Web Workers, and using memoization and virtualization.
Node.js code can contain some computationally complex tasks that will typically block the main thread.

This article explores the ins and outs of multithreading in Node, including some potential pitfalls.
Darcy Clarke, a former npm CLI team manager, discusses a critical issue in the npm ecosystem known as "manifest confusion." This issue arises from the independent publishing of an npm package's manifest and its tarball, without full validation of their contents against each other.

The blog post on Deno's website argues that CommonJS, the module system used in Node.js, is hindering JavaScript's progress due to its synchronous loading and lack of native browser support. It suggests that ECMAScript modules (ESM), which support asynchronous loading and are browser-compatible, are a superior alternative. The post advocates for a complete transition to ESM to better align with modern JavaScript development and the shift towards cloud primitives.
