To access the Fragment component, you can either import it from the React library like this: You should use the React Fragment when you want to add a parent element to fulfill the JSX syntax, but without introducing an extra node to the DOM.Īfter compilation, the fragment component does not make it to the DOM-only the children element do. React Fragment was created to solve problems like this, where you do not want to introduce an extra element to the DOM, and you need a parent element. affect accessibility in cases where the additional nodes may conflict with your semantic elements.produce CSS conflicts if the extra node is not acknowledged in the style declaration.affect the performance of your application (if there are a lot of them in different parts of your application).Sometimes, you may not want that additional node.Īdding extra unnecessary nodes to the DOM can cause one or all of these three things: However, this would introduce an extra node to the DOM. This parent element could be a div, a span, or whatever element that is more semantically correct to serve as the parent. The solution to both blocks would be to add a parent element. The second one would throw an error because the two span expressions do not have a parent element. The first code block would throw an error because there is no parent element before the two child divs. ![]()
