Question

What does this React element look like given the following function?

React.createElement('h1', null, "What's happening?");

Answer 1

The React.createElement function generates an HTML heading with the text "What's happening?". When rendered, it would be equivalent to

What's happening?

in HTML.

Step-by-step explanation:

The React element created by the function React.createElement('h1', null, "What's happening?") would look like an HTML heading element (<h1>) containing the text "What's happening?". When React renders this element into the DOM, it would look like this in HTML: <h1>What's happening?</h1>. This is a simple use case showing how React can create DOM elements without writing HTML syntax directly.
