How to Master Frontend Development: Survival Guide by Lilit Tadevosyan (Arm) | JSConfAM19
summary
Walks through a concrete project: a tiny progressive web app built with server-side rendering, micro‑frontend slices and bundler config that enables dynamic import lazy loading. Uses Chrome DevTools and Lighthouse to measure network and CPU, compares plain JS, TypeScript vs Flow typing ergonomics, and exercises Web APIs (Fetch, WebSocket) for caching and live updates. Shows measured load and interaction improvements after tree‑shaking and lazy loading and whether the approach scales.
