What are the best practices for validation in Angular?

Some best practices for validation in Angular include using reactive forms, leveraging built-in validators, and creating custom validators.

Can you explain how to create custom validators?

Sure! You can create a custom validator by defining a function that returns either null (if valid) or an error object (if invalid).

What are reactive forms and how do they differ from template-driven forms?

Reactive forms are more scalable and provide better control over form state and validation compared to template-driven forms.

How can I handle asynchronous validation?

You can handle asynchronous validation by returning an observable from your custom validator that checks the validity of the input asynchronously.
