How to get error count

[getsetgopi]

As per accessibility requirement we need to show total number of errors in a form.
For example:

1. A form with First name, Last name, email, age, telephone are required field.
2. User clicks on submit without entering any value to input fields.
3. We need to show a message on top of the page as "There are 5 errors". Screen reader will announce this message (helpful for non-sighted user).

I tried error.length and did not work. Want to know how can I achieve this to full fill accessibility requirement.

you will need to use Object.keys with .length instead.
