re: Thanks. I'll look into it

I don't know if useReducer would help all that much TBH, but...

You know, the setState() function returned from useState() can be passed a function, to update the state, which receives the current state and you are expected to return the new state.

setState( state => ({ ...state, updateValue: true }) );

This can be great when dealing with forms.

const [formState, setFormState] = useState({
    name: '',
    age: null,
    level: 1

const handleChange = ({ target: { name, value } }) => {
    return setFormState( state => ({ ...state, [name]: value }) );

return (
        <input name="name" onChange={handleChange} />
        <input name="age" onChange={handleChange} type="number" />
        <select name="level" onChange={handleChange}>
            <option value="1">1</option>
            <option value="2">2</option>
            <option value="3">3</option>

Here's that code a little expanded:

I feel useReducer() doesn't add all that much to state hooks, other than being familiar to redux users. I share some of the reasons for this point of view in this talk if you are interested:
