React was created by Jordan Walke, a software engineer at Facebook. It is a front end library used for handling the view layer for the web and mobile apps. It was first deployed on Facebook’s newsfeed in 2011 and later on Instagram.com in 2012. It was open-sourced at JSConf US in May 2013. It is also useful to create reusable UI components and also can be used with a combination of other JavaScript libraries or frameworks such as Angular JS in MVC.
