How can I handle error messages in Angular forms?

You can handle error messages in Angular forms by using reactive forms and displaying validation messages based on the form control states.

Can you show me an example of how to implement that?

Sure! You can use the FormGroup and FormControl classes to create a form and then use the errors property to display messages.

What types of validations can I use?

You can use built-in validators like required, minLength, maxLength, and custom validators for more complex rules.

How do I create a custom validator?

To create a custom validator, define a function that returns an object with validation errors or null if valid, and use it in your form control.
