ReactJS – Fragments
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
