Angular Signals: Understanding how signals in angular work and why angular signals are important ?

In this video, we will cover everything about the Angular Signals or signals in angular. how to create a signal, set a new value, and how to use update and mutate. Angular signals is a new feature that has been added in Angular 16. signals in angular is like a package that holds a value inside. If the value changes, the angular signal can let other people know. The value inside can be anything, from simple things to more complicated things.
To see what value is inside the signal in angular, we use a special function called a getter. This also helps Angular keep track of where the signal is being used.

28:44 Angular signals vs Change detection
Angular signals are going to be the best features in angular. If we compare the angular signals with the change detection then first we need to understand how the change detection works behind the scene in angular. Angular has overridden some methods from DOM to apply the change on the template and this logic is written in zone.js file. But angular signals do not have any dependency on the zone.js file because they don't have any need for the built method of DOM. And because of this in the future versions of angular this zone.js file will be optional.

THANK YOU SIR 🎉 great job 👍

why to use signals when all these things can be done with normal variables
