"Whether you want to build a note-taking application for mobile devices, an automated testing environment, or demo a live WooCommerce store on your site – Playground will support you."
The last two make a ton of sense, but the idea of building a mobile app that's powered by Wordpress running PHP in webassembly in the browser is wrecking my brain.
Except this is already running on a js environment in the browser (usually v8 if you use chrome, edge or any of their derivatives, the engine behind node). So you are running something to not run the thing you are already running.
There are plenty of Python apps now running in WebAssembly too. A lot of Node's stack directly runs in browsers (browserify is "ancient" tech at this point and influenced so much of modern "bundling" including Webpack and many things post-Webpack). (Deno's doing its own work with browser-compatible Node APIs, too.)
