What is Mounting in ReactJS?
Mounting is the process of outputting the virtual representation of a component into the final UI representation (e.g. DOM or Native Components). In a browser that would mean outputting a React Element into an actual DOM element (e.g. an HTML div or li element) in the DOM tree.
React has four built-in methods that gets called, in this order, when mounting a component:
