TypeError dispatcher.useState is not a function when using React Hooks

Question

I have this component:

import React, { useState, useEffect } from \"react\";
import ReactDOM from \"react-dom\";

function App() {
  const [count, setCount]          


        

Answer 1

Now that react 16.7 (the one not containing hooks) is released you might get an error if you type ^16.7.0-alpha.0 with the leading ^ in your package.json.

For the version with hooks you have to omit the ^.
