AngularJS vs ReactJS

The development of web applications is a complex process. To manage the development staff's workflow as effectively as possible, company needs a tool that features accessibility, proper technical support, high performance and the absence of syntax errors. This article is dedicated to the ReactJS vs. AngularJS stand and compares key features of these two most popular tools for web software development.

Difference between react vs angular and reactjs vs angularjs concepts

Notice that ReactJS and AngularJS have different structures. The main difference between react and angular is the fact that ReactJS is a library but not a fully featured framework, which could make that comparison incorrect at first glance. However, both solutions are dedicated to one objective - creation of user interfaces for web applications.

Furthermore, some non-professionals often confuse react with reactjs and angular with angularjs. As mentioned, for the mobile software developmental purposes Angular 2 proves to be better than React Native, showing much higher level of code security and hack resistance. Why Angular 2? If we talk about Angular 2 benefits, we have to remember, that this framework features TypeScript support (Angular 1 is based only on JavaScript and HTML), which is strictly typified, so that it minimizes the chance of errors.

ReactJS pros and cons

ReactJS is essentially a JavaScript library with open source code. There is a certain list of pros and cons of ReactJS which makes it quite popular among the developers and should be taken into account in order to answer the questions - "Why choose ReactJS and which advantages stamp out its disadvantages?"

Advanced apps' performance. It should be pointed out that the general problem of all frameworks working with JS is actually its fall behind the  applications developed on their foundation, because of the user interface, which tends refresh a large number of UI components in response to the actions of users. In turn, due to functionality of the ReactJS, developers are able to create automatically updated one-page applications that do not require a reload for the UI redraw (therefore, they also do not require user's extra effort and internet connection, which decreases loading of devices' operating systems). The process implies the use of "lightweight" Virtual DOM (apart from DOM browser) instead of real DOM tree. This way, even the applications with quite complicated and numerous logical constructions, which may lag on the devices with poor technical specifications regardless, are perceived by a user as "responsive" (i.e. animation or interface's reaction on finger and touch screen contact have delay of no more than 16 ms). We have also to take into consideration, that ReactJS provides an advanced apps' performance rate among other JavaScript frameworks. It is even possible to visit famous ReactJS websites such as: Yahoo, Mail or the New York Times official website to assure oneself in the effectiveness of ReactJS platform and, as a consequence, the higher level of productivity.

One of the most outstanding feature of React is a pretty simple mastering. In distinction from AngularJS (especially Angular2) one will not need the strong user guides to work with React. Everything, what is needed is just the acquiring skills in JSX, that, as well as HTML, implies the declarative coding style. However, everything is not so simple if we are talking about the architecture of ReactJS - Flux. Some developers consider it to be pretty simple for understanding while others strongly doubt its accessibility for beginners. Either way, Flux, featuring one way data binding, proves to be a decent alternative to traditional MVC and MVVM models and provides more rational approach to work with DOM. Therefore, the winner of the angular vs. react js 1st tour competition deservedly could be the second option.

Developmental flexibility is one of React's stronger features. Having an opportunity to connect the functionality of side-libraries, developers can choose the most optimal ways of implementation of capabilities in their front-end projects. On the other hand, AngularJS provides developers with limited capabilities featured by default in its current version. The fact that ReactJS is based on View template (AngularJS, in its turn, is based on MVVM model) and focuses exclusively on the description of data transmission, augments an additional flexibility. 

The rest of app's components can be chosen by developer's preference. Let us also notice that React Native can be utilized in cooperation with standard platform's components such as: Drawer for Android or UITabBar for iOS. All the actions taking place between JS and native platform are ordered asynchronously, providing extra versatility of the developmental process.

Inspecting the disadvantages of ReactJS.

One of the most vital drawbacks could be the absence of single development environment. As it was already mentioned before, ReactJS is not a framework and the developers can require side-libraries' components. Consequently, if time dedicated to project's development is strictly limited, ReactJS will unlikely be a good choice.

Repeated rendering. Repeated rendering can slow the application's performance down. Despite of the fact, that React Fiber algorithm is being actively prepared for the release to eliminate this problem. However, currently, there are no proper mechanisms for the increase of response in applications with capacious updatable components and numerous logical operations that have to be executed simultaneously.

AngularJS pros and cons

AngularJS is a full-featured development environment with open source code. It is also actively applied in the development of one page web-applications with the usage of JavaScript. So, let us list the key positive sides of angular.

First of all, the framework was initially based on MVC template, which is essentially a scheme that separates software into three parts: model, view and controller. Such scheme gives the developer an opportunity to divide the creation of program's components using the same data. Furthermore, nowadays, AngularJS has switched to MVVM (Model-View-ViewModel) template in order to provide an opportunity to separate application's logic from its representation in UI.

Then, two way data binding provides association of two compared DOMs, so that they can be refreshed simultaneously. This involves more technical resources, but increases the level of response to user's' actions.

Lastly, unlike any other acknowledged framework, AngularJS features quite capacious, but incredibly detailed documentation, in which one can find an answer to practically any question as to the development in this environment.

Enlightening the disadvantages of AngularJS.

The already mentioned two way data binding uses the resources a mobile device's operating system quite irrationally and that can cause early battery's "death". That actually means, that Angular JS is suffering from such a crucial drawback as the relatively low performance.

AngularJS syntax could be defined as a quite complex  especially for the beginners. On the one hand, strict predetermination of commands decreases the risk of errors, while on the other hand it makes unfamiliar code difficult to understand.

Rivalry between AngularJS vs React JS: summary

All in all, we have successfully analyzed the difference between angular and reactjs, now, let us make a summary. Because of the emergence of more and more advanced tools dedicated to advance the level of applications' response,  the most versatile one of them. Having considered all the aforementioned AngularJS and ReactJS advantages, we made a conclusion that if you are looking for a tool that will help you discover the most flexible ways of web application’s capabilities realization and is utterly simple to master - ReactJS is your choice. The flipside is that AngularJS is an appropriate choice for those, who desire the integral approach to the web development and maximum productivity of team work.
