The essential core of web development has been HTML, CSS, and JavaScript HTML, as we know, is hypertext mark-up language. It is the skeleton of any webpage. It places the header, the text and the side-bar. CSS is style sheet language which adds style, e.g. fonts, spacing, colours to the elements of the web. JavaScript is programming language and serves as an interface between the webpages and the user.

Over a period of time, new tools and libraries have been developed. It qui-ckens web development. A library is collection of resources, e.g. pre-written code, configuration data and message templates. ‘React’ is one such library developed by Facebook engineer Jordan Walke. It was initiated in 2013 by open sourcing it. It is a JavaScript library to manage the increasing number of elements on the Facebook page.

React developers are in demand. Many organisations have adopted React. A React developer already has mastered HTML, CSS and JavaScript. He then builds small apps using React to make himself marketable. He makes small open source projects.
