Advantages of React JS: Open-source JavaScript Library
Due to the growing popularity of reactive approaches to software development, programmers are now turning with more and more interest to React JS - open-source JavaScript library that solves problem of fast visualization of a big dataflow and simplifies creation of interactive user interfaces.When it is needed to display dynamic content, template engines are used. They work pretty simple: to the existing template a specific set of data is applied and some of dataset representation is obtained. If data is changed, it has to be displayed in a representation. A programmer needs to write the code which alters representation and synchronizes data changes in one. But, if we already have a template, why don’t we use it?
