What is it React JS?
It makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.
React has become the tool of choice for easily building dynamic user interfaces. The power is in the Virtual Dom — when your application's data changes, React figures out which parts of your document need to be changed, and immediately update only those parts.
