The httpResource API is still experimental, but it will most likely replace all our usages of HttpClient in the near future, which is why I’m excited to share this now!

What setTimeout Really Does in Angular
In JavaScript, setTimeout queues a task on the macrotask queue to be run after the current call stack clears. In a normal JS app, this is predictable.

But Angular isn’t just JavaScript — it uses Zone.js under the hood.

Zone.js monkey-patches setTimeout so Angular can trigger change detection after async operations.

Every time setTimeout fires, Angular knows something changed. So it runs its entire component tree check cycle.
