Write a React Component from Scratch getElementById is not defined

I have the first two items but not the last.
error: MyComponent should render to the DOM.
I’ve spent 45 minutes researching and can’t find the issue.
I get “Uncaught ReferenceError: getElementById is not defined”, but I’ve even copied and pasted that from the example and it doesn’t work.


Your code so far

// change code below this line
class MyComponent extends React.Component {
  render() {
          <h1>My First React Component!</h1>
//  I also tried adding this div at this point in the code: 
<div id="challenge-node"></div>, but no difference//

ReactDOM.render(<MyComponent />, getElementById('challenge-node'))

Link to the challenge:

This is the first Google result for getElementById:


document.getElementById(/* whatever the Id is */)

It’s provided by the browser, it’s a method on the document object, you can’t miss out the document. bit
