💡 Background and solution

Background:

In the old code, the type of defaultValue is T | IFuncUpdater<T>, IFuncUpdater is as follow:

export interface IFuncUpdater<T> {
  (previousState?: T): T;
}

This means that if defaultValue is a function, it can accept a previousState parameter, but actually, it makes no sense to do so, and there is no parameter was passed to defaultValue in real code.

So, defaultValue type just should be:

defaultValue?: T | (() => T);

By the way, this PR also do some other changes, as follow:

1. remove useless /* eslint-disable */

2. remove useless type definition

3. simplify code:

   from:

   const [state, setState] = useState(() => getStoredValue());

   to:

   const [state, setState] = useState(getStoredValue);
