We know that we make use of render method inside a component whenever we want to render something to the screen. We may render a single element or multiple elements, though rendering multiple elements will require a ‘div’ tag around the content as the render method will only render a single root node inside it at a time.
As we saw in the above code when we are trying to render more than one root element we have to put the entire content inside the ‘div’ tag which is not loved by many developers. So in React 16.2 version, Fragments were introduced and we use them instead of the extraneous ‘div’ tag.
The output of the previous code and the code above is same but the main reason of using is that it is a tiny bit faster as when compared to the one with the ‘div’ tag inside it, as we didn’t create any DOM node. Also, it takes less memory. Another shorthand also exists for the above method in which we make use of ‘<>’ and ‘</>’ instead of the ‘React.Fragment’.
