ReactJS – Fragments

ReactJSWeb DevelopmentFront End Technology

While building a ReactJS application, all the JSX code needed to be wrapped down inside a parent tag.

ReactJS Fragments were introduced with React 16.2 version to remove the need to define an extra <div> tag which also takes extra memory.

Without Fragments

The following sample code shows how to create a simple React application without React Fragments.

Example

App.jsx

import React from 'react';

class App extends React.Component {
   render() {
      return (
         <div>
            <h2>TutorialsPoint</h2>
            <p>Simply Easy Learning</p>
         </div>
      );
   }
}
export default App;

Output

Using Fragments

In the above example, we have to use an extra <div> tag to wrap the children JSX elements. So with ReactJS 16.2 version, we will use the React.Fragment which will remove the need to use an extraneous <div> tag.

Example

App.jsx

import React from 'react';

class App extends React.Component {
   render() {
      return (
         <React.Fragment>
            <h2>TutorialsPoint</h2>
            <p>Simply Easy Learning</p>
         </React.Fragment>
      );
   }
}
export default App;

Output

Shorthand of Fragment

We can also use <>, instead of React.Fragment but this shorthand syntax does not accept key attributes.

Example

import React from 'react';

class App extends React.Component {
   render() {
      return (
         <>
            <h2>TutorialsPoint</h2>
            <p>Simply Easy Learning</p>
         </>
      );
   }
}
export default App;

Output
