How can I implement custom error messages in Angular form builder?

You can implement custom error messages in Angular form builder by using the setErrors method on your form controls.

Can you give me an example of how to use setErrors?

Sure! You can use it like this: this.myForm.get('myControl').setErrors({'incorrect': true}); This will set a custom error.

What if I want to show different messages for different errors?

You can create a method that checks the errors and returns the appropriate message based on the error type.

Is there a way to display these messages in the template?

Yes! You can use *ngIf to conditionally display error messages in your template based on the control's errors.
