MDN swaps React for Lit frontend overhaul

MDN adopting Lit over React is the ultimate endorsement of native web standards for content-heavy sites.

• –Migrating to Lit web components allows MDN to seamlessly embed interactive features like live playgrounds directly into static HTML without full framework overhead.
• –Server-side rendering using Declarative Shadow DOM ensures styling and structure are fully intact before any client-side JavaScript executes.
• –Replacing Webpack with Rspack slashed local development startup times from 2 minutes to just 2 seconds.
• –The shift to an "islands of interactivity" model proves that treating the DOM as the source of truth is still a winning strategy for web performance.
