Ehem, #JavaScript also uses the backslash as a separator in the URL.pathname, like '/'. Firefox dev console, but node is similar:
% let a = new URL("http://localhost/abc\\def")
> undefined
% a.pathname
> "/abc/def"
Can anyone point to a spec where this is described?

Under the Hood of MDN’s New Frontend, by @leo.mca.is (@mdn):

https://developer.mozilla.org/en-US/blog/mdn-front-end-deep-dive/Cool to see #MDN exploring a unique #frontend architecture which better meets their needs.

A lot of the core ideas here are stuff I've been trying to formalize in #HydroActive and #rules_prerender. Islands of reactivity on a mostly static page and driving resource loading by what gets rendered are both key features most FE systems lack.
Under the hood of MDN’s new frontend. Leo McArdle explains how the MDN team replaced their aging React-based SPA with a modern architecture built on web components and Lit. The new setup uses server components for static templating, lazy-loads interactive elements as custom elements, and leverages Baseline to decide which web APIs to adopt. The result: a dev environment that starts in 2 seconds instead of 2 minutes. #mdn #webcomponents
