clearing errors object when to return errors: {} from a resolver

Is your feature request related to a problem? Please describe.

1. mode: onChange
2. use validationResolver
3. have errors in more than one inputs
4. validate all inputs by one of the inputs, and return errors: {} in the resolver

Currently errors: {} doesn’t clear const {errors} = userForm() this errors object entirely. resolver only updates the errors for the specific input you change.

Describe the solution you’d like

I would like to see errors object being cleared to {} by giving errors: {} from a resolver.

Describe alternatives you’ve considered N/A

good point @github0013 i will re-open this issue and update the documentation, so others people aware of this issue and the reason behind this decision.

ok @github0013 i have completely my investigation. Short story, i think we will keep what we got for now. Let me explain the reason behind. Feel free to leave your thoughts as well.

The way we trigger re-render is based on error appear/disappear: https://github.com/react-hook-form/react-hook-form/blob/master/src/useForm.ts#L563 which is one of the performance enhancement for this library. If an error is persist then there is no need to re-render, so does when an error gets resolved, and it’s cheap to running against a single error at a time. We can invest into errors object comparison, but then it’s not efficient at least with my estimation for now. so for conclusion, we will keep as it for now.

let me know if this make sense.
