The effect function in Angular runs a callback when a signal value it depends on changes. The callback is also invoked when the component first renders.

An effect can depend on multiple signals or computed signals. When any of these signals change, the effect callback executes.

Instead of running effect in the constructor, it's best to assign it to a component property. This allows for manual interaction with the EffectRef if needed.
