A Factual Analysis On AngularJS Vs. ReactJS

ReactJS vs Angular Comparison

If you own a technology-oriented business, you always have to update and improve your products or services to avoid obsolescence. If you own a website or mobile app, you understand the importance of selecting the correct option between various JavaScript frameworks.

Choosing between various frameworks like AngularJS, ReactJS, NodeJS, etc. is not a walk in the park.

I am here to help you get a little closer to deciding between two frameworks; AngularJS vs. ReactJS. Honestly, comparing these two frameworks is not a fair comparison as Angular existed longer than React, so the more popular framework is undoubtedly the AngularJS framework.

Just because Angular JS is more popular doesn’t exactly mean it’s better than React JS. The ReactJS framework makes a developer more skilled in JavaScript, as it requires more knowledge of it.

Many such Pros and Cons exist for the two best JavaScript frameworks that we will provide you with in this blog. But, you need first to know what Angular.JS and React.JS are.

What is AngularJS?

Developed by Google, Angular made its way to the market in the year 2009. Angular offers solutions for almost every aspect of front-end development because of its full-stack framework. Angular uses JavaScript to develop web pages as well as browser apps on the MVC base.

Angular is a perfect framework to implement in classic applications of an office environment unless it has to process a large amount of data. This would restrict the possibilities of interaction. The loading time gets reduced as now Angular uses MVVM (Model-View-ViewModel) instead of MVC (Model View Controller).

Advantages of AngularJS

A wide-open source community backs AngularJS development for many good reasons, and we present to you some of the top reasons why to go with Angular:

  • Two-Way Data Binding: Building a connection between the application UI and business logic is of utmost importance for the app’s usability. This Data binding is done fast and smoothly by AngularJS as it offers three types of data binding to overcome any problem in app functioning. One of the three data binding types is Two-way data binding. This Two-way binding ensures that any changes made to the data are instantly synchronized to all views and models.
  • Development And Testing: Angular development frameworks make highly testable websites and apps using end-to-end testing and unit testing. This reduces the time and effort given to testing and debugging. For fast learners, Angular becomes familiar in very little time, giving them more time to experiment with features. With dependency injections, Angular allows various chunks of code to be isolated and tested separately.
  • Polygamous Working: AngularJS framework allows its users to work in different environments, including JavaScript, CoffeeScript, Dart, TypeScript, Pure HTML, etc. In fact, it has morphed into a full-fledged platform where you can implement outside directives increasing functionality.

Disadvantages of AngularJS

Every mirror has a black side, and so does Angular. There are some significant drawbacks to using Angular; some of the more prominent are:

  • Difficult To Learn: Angular is quite time-consuming and tough to learn. With limited documentation available, this problem is further increased. Even with an elaborate and simple manual, its learning curve is quite steep. New developers may find AngularJS very complex.
  • Security Needs Additional Attention: JavaScript being open-source is always at high risk of security breach. A programmer needs to give more time and precaution on security in the development of apps. This makes working in an Angular framework more time-consuming. There exists a solution for this in the form of Angular Universal.
  • Issues In Data Binding: With two-way data binding, there exists an issue if the existing data model is altered in any way. This troubling factor becomes the source of deteriorating framework performance.

Well, this was just one side of the coin named AngularJS vs. ReactJS. Now let us have a look at ReactJS development.

What is ReactJS?

With its advent in May of 2013, the Facebook-developed ReactJS framework came in with a sweeping blow to existing frameworks. React is considered the second most famous JavaScript framework; if you are looking to build an app with many dialog elements to interact with a whole other lot of elements, then React should be your choice of framework. With higher performance stability, React takes away the cake for interactive website building.

ReactJS is an open-source framework that can build an app that can update in various instances without the page having to load manually. It uses one-way data binding instead of two as in Angular, which renders both server and client-side.

React works with a virtual DOM instead of a regular one. The Document Object Model (DOM), a programming interface, makes the rendering quicker by updating the interface when data is changed. AngularJS uses real DOM instead of virtual like ReactJS.

React is preferable to Angular when a higher amount of data is to be processed. Now, let’s get more specific with the Pros and Cons of ReactJS:

Advantages of ReactJS

  • Open Source Library: Being open-source, the React framework accepts contributions in coding or other technical ideas and suggestions from developers worldwide, making React more prone to improvement via updates.
  • JSX: JSX is a JavaScript syntax, which is used to render components by allowing HTML quotes and tags. Using JSX, you can read and compile machine language, all in the same space.
  • Multi-platform Nativity: With the ReactJS framework, you can build Android and iOS in the respective native platform. Many social media platforms are built using ReactJS like Facebook, Instagram, Twitter, Pinterest, and LinkedIn.

With every coin having two sides, we must also consider using ReactJS to find the best result for AngularJS vs. ReactJS.

Disadvantages of ReactJS

  • Not Fully Scalable: The need for more deep insight is a must for React as it doesn’t have a fully scalable framework. More knowledge is required even to integrate User Interface (UI) into the MVC framework.
  • Frequent Re-render: There is a continuous re-rendering that leads to the slower performance of the application, making it difficult to handle large data chunks.
  • Inexperienced: As React has only been around for 4 years, it’s still fresh and has very few tutorials and support videos that programmers can view to learn. This leads to a slower learning process than other existing frameworks.

There are many differences and some similarities between ReactJS development and AngularJS development. So making an appropriate comparison of ReactJS vs. AngularJS can be tough and yet needed.

Comparing AngularJS vs. ReactJS can lead to an undecided output or a clear winner according to your individual preference. In Angular, you pay for safety by sacrificing flexibility while React gives you a more contemporary framework to work on.

Building a good framework is not enough these days. Nowadays, the toolchain and the ecosystem are much more important than the framework itself. An example of that is that most modern IDEs support Angular and React.

We can say that Angular and React are solving the same problem with different approach. It’s up to you which approach fits your preference and liking.

Did you get your clear winner framework? Now you may be looking forward to hiring an AngularJS developer or ReactJS developer. You can search for such developers at different web portals and conduct interviews with possible candidates.
