Learn how Ember’s @tracked decorator replaces observers, how the dirty‑bit mechanism keeps updates granular, and what common pitfalls to avoid. A hands‑on guide with code, migration steps, and testing tips.
Autotracking in Ember records what a template reads, not how you mutate data. Learn why push on a plain array is silent, how @tracked getters replace computed properties, and when to reassign or use tracked-built-ins.
Learn how to replace legacy computed properties and observers with Ember's @tracked system to eliminate dependency arrays and improve application performance.
