What does the status property of a form do?

The status property of a form (or of any control: FormControl, FormGroup, FormArray) shows its current validity state as a string.

It can take one of four values:

• VALID - all checks pass;
• INVALID - at least one validator fails;
• PENDING - an asynchronous check is in progress (for example, a request to the server);
• DISABLED - the form or field is disabled and does not take part in validation.

Example:

This property is convenient for reacting to state changes, for example to enable a button only when VALID.
