The Significance of Virtual DOM in ReactJs ..!
The virtual DOM is a programming concept where a virtual representation of a User Interface is kept in memory and synced with the Real DOM. In React context, the Virtual DOM is React’s local and simplified copy of the HTML DOM. ReactJS is the first framework to take this to an obvious conclusion: optimizing for DOM manipulation leads to a fast library, and in this case, a library which enables web applications that require very little code.
