DOM Manipulation is the process by which one can dynamically change the content of the web page. Working with DOM should be fairly easy and quick as it is always tree-structured, traversing the DOM is easy. React can figure out which objects have been changed, and this process is called drifting. The changed objects will get updated on the Real DOM. The new element will be added to the end of the list, and the entire tree will be rebuilt again as the new element is added.
