Angular Signals update function

We have a signal value with an object type and want to update one or some of that object's values.

In this case, we can use the Angular Signals update function and JavaScript spread syntax:

this.user.update((user) => ({ ...user, fistName: "First name updated!" }));
// or
this.user.update((user) => ({ ...user, fistName: "First name updated!", lastName: "Last name updated!" }));
// or
this.user.update((user) => ({ ...user, ...this.curUser }));

I hope you found it helpful. Thanks for reading. 🙏
