AngularJS is a complex structure with a diverse variety of services, controllers, directives and other components, which helps to provide maximum functionality. In the process of the framework development, developers have settled up their vision of an ideal application structure. So if you follow the rules, everything’s going like clockwork, but any deviation from the very architecture will cause a number of complications, that will certainly influence on the development procedure.
The opposite thing has implemented by ReactJS inventors, they build a number of architecture options, so developers could choose tools on their own peril. The code, written in React is simple and structured (but shortness isn’t it’s forte). But we have a nice bonus – lazy loading of components, that really accelerates work. Also, React has it’s own application architecture Flux for creating web-apps on the Client’s side
AngularJS adapts and extends the traditional HTML, thus providing double-sided binding of dynamic content data. Code lengths minimize this gives us an opportunity to synchronize model and presentation automatically. In this way, framework, that was kindly presented to us by Google company, declines the role of DOM-manipulation. It is much easier to test the code. In 2012 Google Chrome extended the Developer Tool, by adding Batarang plugin, so now debugging and profiling of web-applications is much easier, also.
Unlikely it’s opponent, React uses one-way data binding. This makes the conceptual basis, it is always clear from which place and in which condition arrived modified data. In 2015 React got native library ReactJS Native for mobile apps development under IOS and Android.
Despite the short code of Angular, there still may appear some bugs while processing massive data sheets. The reason – double-sided data binding., each element requires its own processor. In the result, the more data of such kind – the lower performance will be.
React uses DOM to process data. It structures the list of changes and strictly follow it, without changing other elements. So for processing Big Data, this tool rather matches. Gain your points for performance, React!
To resume, both competitors, as AngularJS, as ReactJS have their strong points. So it’s necessary to analyze all nuances of the project, that you are going to implement, to be sure that you have chosen the proper one.
