Using Dynamic Var with `Set` State in React Hooks?

Question

You could use a single useState with a default value of an object that contains all your input values and update that like you are used to with class components.

Example

const { useState } = React;

function App() {
  const [state, setState] = useState({ email: "", password: "" });
  function onChange(event) {
    const { name, value } = event.target;
    setState(prevState => ({ ...prevState, [name]: value }));
  }

  return (
    <div>
      <input value={state.email} name="email" onChange={onChange} />
      <input value={state.password} name="password" onChange={onChange} />
    </div>
  );
}

ReactDOM.render(<App />, document.getElementById("root"));

<script src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>

<div id="root"></div>
