<p>Reactive programming is carried out using the building blocks of functional programming. JavaScript libraries such as ReactJS are used for front-end web development that is both competent and powerful. ReactJS is intensively being used to develop webapps for Facebook.</p> <p>This title is among the first of those addressing how everyday programmers can take advantage of reactive programming without having an extremely heavy mathematical background. It starts with the basics a front-end developer can easily connect with, while also covering the basics of functional programming. Then it goes on to explain non-functional reactive programming with the help of a live example. After that it gives a theoretical overview of reactive programming supported by functional programming. Tools to make functional programming easier like Bacon.js, a library like jQuery, are also covered. Finally, it finishes with building one small and one larger front-end project.</p>
