Introduce the useFormStateSelector hook #413

Closed robin-ambachtsheer closed 2 years ago

robin-ambachtsheer commented 2 years ago

This hook is all about preventing unnecessary re-renders in your React components.

const someField = useFormStateSelector((formState) => formState.values.someField);

return someField; // re-renders when formState.values.someField is changed
