Build a Markdown Previewer(Issue Resolved)

Tell us what’s happening:

The text I have typed in wont display.
Can someone please help me.
I've done research on the internet, I am just not having luck finding an answer.

Your code so far

<div id ='root'>

class App extends React.Component {
  render() { 
    return (
    <div> Markdown Previewer </div>

ReactDOM.render(<app/>, document.getElementById('root'))

Did you remember to import React? A link to the actual project would be helpful. One thing I do notice right off the bat though is that your class App is capitalized, but your ReactDOM.render call has <app/> instead of <App/>.

Yes I did remember that. I figured it out. I know I for got to capitalize the A in app.
Thank you for helping out.
