Dynamically Create HTML Elements

An HTML element can be created with a string that matches a recognized entity.

const Paragraph = 'p';
return <Paragraph>Some paragraph content</Paragraph>

This means we can dynamically create HTML elements such as headers:

const H = ({ level, ...props }) => {
  const Heading = `h${Math.min(level, 6)}`;
  return <Heading {...props} />;

return (
    <H level={1}>Header 1</H>
    <H level={2}>Header 2</H>
    <H level={5}>Header 5</H>

With some inspiration, I’ve created a live example here.
