Why are Fragments in React 16 better than container divs?

When working with React, you may have come across the need to wrap multiple elements in a container. Traditionally, developers have used a

element as a container. However, with the introduction of React 16, a new feature called Fragments has been introduced, which offers a better alternative to using container divs.

What are Fragments?

Fragments are a way to group multiple elements without adding an extra node to the DOM. They allow you to return multiple elements from a component’s render method without the need for a container element.

The Benefits of Using Fragments

Using Fragments instead of container divs offers several advantages:

Improved Performance: Fragments don’t create an additional DOM node, resulting in faster rendering and improved performance.
Cleaner HTML Structure: Fragments help to keep your HTML structure cleaner by eliminating the need for unnecessary container divs.
Reduced CSS Complexity: With Fragments, you don’t need to worry about styling container divs or dealing with CSS specificity issues.

How to Use Fragments

Using Fragments in React is straightforward. Instead of wrapping your elements in a

, you can use the component or the shorthand syntax <>.

Using the Component:

{`import React from 'react';

function MyComponent() {
  return (
    
      Hello
      World
    
  );
}`}

Using the Shorthand Syntax:

{`import React from 'react';

function MyComponent() {
  return (
    <>
      Hello
      World
    
  );
}`}

Conclusion

Fragments in React 16 provide a cleaner and more efficient way to group multiple elements without the need for container divs. By eliminating the extra DOM node, Fragments improve performance and help maintain a cleaner HTML structure. So, the next time you need to wrap multiple elements, consider using Fragments instead of container divs.
