The React Fragment: Creating Invisible HTML Tags

In React, when you want to return more than one element from a component, you usually wrap them in a div to satisfy the requirement of returning a single element. However, this approach adds an unnecessary div to the output. To avoid this, you can use React.Fragment.

Here’s an example of how to use React.Fragment:

import React, { Component, Fragment } from 'react';

class BlogPostExcerpt extends Component {
  render() {
    return (
      <React.Fragment>
        <h1>{this.props.title}</h1>
        <p>{this.props.description}</p>
      </React.Fragment>
    );
  }
}

In recent releases of React (and Babel 7+), there is also a shorthand syntax available using <> and </> for React.Fragment:

import React, { Component, Fragment } from 'react';

class BlogPostExcerpt extends Component {
  render() {
    return (
      <>
        <h1>{this.props.title}</h1>
        <p>{this.props.description}</p>
      </>
    );
  }
}

Using React.Fragment or the shorthand syntax <></> allows you to group multiple elements without the need for an additional container tag like div.
