React Fragments and Portals Usage
React Fragments and Portals are advanced features that enhance the management of component structures and DOM nodes in React applications. Fragments allow developers to group multiple child elements without introducing additional nodes into the DOM, keeping the component tree clean and efficient. This is particularly useful for returning multiple elements from a component's render method without affecting layout and styling. Portals, on the other hand, provide a way to render a component outside its natural parent hierarchy in the DOM, which is ideal for creating overlays like modals or tooltips that need to escape the constraints of their parent containers for better visual placement. By leveraging these features, developers can create more organized, flexible, and maintainable code.
