Fully Zone-Less - High-Performance Angular applications in post IVY
summary
Argues that zone.js is the biggest enemy and shows concrete techniques to get zone-less rendering inside a zone-full app: measure with flame charts, use Chrome’s task-priority APIs and requestAnimationFrame to coalesce microtasks into one render, switch to push-style bindings and OnPush/select slices of state, render embedded views instead of full component trees, and throttle updates so dozens of renders (example: 12 → 1) and heavy lists (example: ~900 items) become a single non-blocking paint.
