React abstracts away the DOM from you, giving a simpler programming model and better performance. Since it uses Virtual DOM, it also reduces browser reflows and repaints. React can also render on the server using Node, and it can power native apps using React Native.
React implements one-way reactive data flow which is easier to reason about than traditional data binding.
React can be included from the following CDN locations for the purpose of tutorials.
