The Unbearable Weight of Massive JavaScript

on YouTube ↗53m

" summary

Claims a 55,000-line JavaScript codebase shrinks to 650 lines and time‑to‑interactive drops from about 12s to ~3s by prioritizing progressive enhancement and platform APIs. Uses import maps to avoid heavy bundling, custom elements for encapsulated widgets, scroll‑linked animations and view transitions for GPU‑accelerated visuals, plus the navigation API to handle soft navigations. Builds an e‑commerce site, replaces SPA complexity, and reports the result actually works and measurably improves performance.
