Polywasm: A Polyfill to Run WASM in JS Environments — The creator of esbuild is back with something fresh: a polyfill that uses live translation to be able to run .wasm files in JS environments that either lack a WebAssembly implementation or have it disabled. You can see how it performs in this special version of the esbuild playground.
Evan Wallace
Announcing TypeScript 5.1 — This release of the statically typed JavaScript superset is a gentle ‘quality of life’ step forward rather than a featureful extravaganza, but we get support for linked editing of JSX tag names, namespaced JSX attributes, the ability to have unrelated types for getters and setters, and undefined-returning functions no longer need an explicit return.
