javascript - My output refused to change after i changed the code in the ReactDOM.render() method in my index.js file

Solution:

You have two ReactDOM.render, remove the first one with the component.

You will be left with this code:

ReactDOM.render(<h1> Hello, React! </h1>, document.getElementById('root'));

It should work like this.

Solution:

Remove the first render... You have 2 render... Js runs from top to bottom, so it's rendering the first one
