Invalid Component Element in React.JS

Question

I\'ve been going through a react.js tutorial, with a simple hello world example. I can\'t find a reason why the following shouldn\'t work, but I keep getting this error.

Answer 1

You should pass to render <HelloWorld />, not new HelloWorld()

React.render(<HelloWorld />, document.getElementById("test"))

Example

jsx-in-depth

Or you can use React.createElement, like so

React.render(React.createElement(HelloWorld, null), document.getElementById("test"))

Example
