Signals are a pretty big deal in Angular now-a-days. I’ve created several videos on them recently because there’s a lot to consider when using them. As you use them more over time, you’ll probably run into scenarios where you need to execute code when signal values change.

We’ll if this is the case, there is another possibility. You can use the effect function.
