About React
React is an open-source project created by Facebook first launched in 2013.
React is a popular JavaScript library
It is used to build fast and interactive complex client-side user interfaces for both web and
mobile applications
It is responsible only for the application’s view layer. It is the view layer of an MVC application
(Model View Controller)
It is component-based. Reusable components are the building blocks of React
React uses Virtual Dom (like a lightweight copy). It allows React to do its DOM manipulations faster
than using Regular DOM. Thus, it makes the web applications run much faster than those developed
with alternate front-end frameworks. See React and the Virtual DOM.
React is easy to learn, as it mostly combines basic HTML and JavaScript concepts with some
beneficial additions
Chrome has extension for React debugging
