Enhancing Performance by Leveraging the Power of Observables
summary
Demonstrates using Observables (Rx) to drive view updates instead of the framework’s default change detection to reduce unnecessary work and improve performance. Shows a live 60fps timer and a slower counter with flame charts proving that replacing default detection with observable-driven updates and manual subscription points (or a small polyfill layer) cuts long task times from ~100ms to single-digit ms.
