ReactJs dynamic object name in function

Question

I want to pass dynamic object name to a function:

handleValid = (type, v) => {
  const validationError = RequestValidation.????.submit(v); // but this is call an object
  const value = v; // this is value
}

Here is I pass two parameters to function:

this.handleValid(Object.keys(doValid)[i], Object.values(doValid)[i]);

So type parameter is dynamic, I don't know how can I set dynamic object name here, what I searched and tried:

const validationError = RequestValidation.[type].submit(v);

Or should use something like:

[`${type}`]

Of course this not working:

const validationError = RequestValidation.type.submit(v);
