How to change “This is required field” message to field-wise magento 2 customer registration

Question

If I am submitting registration form as blank then all fields are showing an error message:

This is required field

I want to change this message according to fields.

For Example:

> > First name is required
 
> > Last Name is required
 
> > Email is required

You can use data-msg-required attribute in all form fields and you can pass your custom message there.

For ex. for an input field you can use like this..

<input type="text" name="firstname" data-msg-required="Firstname is required." data-validate="{required:true}" />

Hope this will help you!
