Creating useState() - I'm soooooo clever

useState-ehm-nope.js

const useState = (initValue) => {
    let state = initValue;

    const setState = (newState) => {
        if (typeof newState === 'function') {
            state = newState(state);
            return;
        }
        state = newState;
    }

    return [state, setState]
}

const [myState, setMyState] = useState('test');

setMyState('test2')
