There is a considerable amount of debate on whether ReactJS vs AngularJS is a smarter choice for front-end development. According to the recent stateofjs.com framework comparison React is regularly used by 65%, while 19% plan to learn it. While 24% use Angular and 34% are keen to learn it. ReactJS and AngularJS are the robust development technologies. They are built on Javascript that clubs advancement and customization to develop advanced web applications.

Our article provides a comparison of how both AngularJS and ReactJS intend to solve the similar front-end challenges, but with a difference in approach and philosophy. AngularJS is designed and managed by Google. Learn more about the features of Angular 7. A popular JavaScript Framework, it powers 1,471,509 live websites today. While ReactJS powers 305,267 live sites. Learn more about the business benefits of ReactJS for modern web & app development.

AngularJS Vs ReactJS: Framework Against Library

Both these frameworks are here to stay with today’s technology ecosystem fueling with Mobile Apps and Web Apps. With the rising popularity of ReactJS and its ease of adoption, there is a significant rise in its adoption. However, AngularJS continues to be one of the top JavaScript Framework while ReactJS is yet to take the test of the time to handle websites that are of Medium to High complexity. Prompt rendering and the presence of JSX is making ReactJS, the resultant workflow stack as a highly impactful JavaScript framework. Of course, the resultant workflow of this stack is much different. Hence, AngularJS and ReactJS comparison is moot.

While picking up the right front-end application development technology depends upon the end user requirement, the below points will help one to make a conscious decision beforehand.

The primary difference between AngularJS and ReactJS lies in the state of its management. Angular has data binding bundled in by default, whereas React is generally augmented by Redux to give unidirectional data flow and work with immutable data. Both are opposing approaches and there is no consensus on what is better: mutable/bi-directional data binding or immutable/unidirectional.

  • Implementation
    AngularJS is a framework that provides a large number of native options and features. It allows you to benefit from a number of options directly, which makes it possible to start a project faster without being intimidated by the choices to be made at startup.When comparing React JS Vs Angular JS, it is important to know that ReactJS is an open source JavasScript library. Hence, you need to add external component libraries to have the same number of features. You will need to add elements for “routing” to force unidirectional flows, to call APIs, set up tests, manage dependencies, and more.
  • Data Binding
    AngularJS uses a two-way data binding which connects the Document Object Model (DOM) values to model data. It means, if for user interaction with the field a new value is provided to the app it will result in the update of both the view and the model. In addition, it helps write less boilerplate code to include the interactions between components in your app. However, the two-way data binding approach has a negative impact on performance.ReactJS supports one-way binding. It provides singular behavior for your application. The implementation of dependencies helps the singularity to separate from the classes and the risks of error can be minimized. Also, the one-way data flow in React helps to control the complexity. So, it’s much easier to debug the self-contained components of large React applications similar to larger Angular JS applications.
  • Architecture
    AngularJS is based on the MVVM (Model-View-View-Model). It comes with an exhaustive list of tools as well as features such as data link, change detection, forms, routing, navigation, HTTP implementation and many more.React only covers the MVC (Model-view-Control) model, so you will have to use other libraries like Redux and Flux as a controller or react-router for navigation.
  • Performance
    Angular’s MVVM offers the advantage to reduce the loading speed of the web pages considerably. Further, the communication is in the asynchronous mode. It reduces the number of entrances to the server. Since the visual interface is on the client side, part of the back-end queries is removed. It improves the speed of designing web applications.

    Overview Of Usage Stats Of Frontend Development Framework

    ReactJS creates its own virtual DOM where components are attached. It brings the comfort of navigation within a web site since all the data get displayed without refreshing the page. Everything is then more fluid and fast!

    Angular JS offers low performance with complex and dynamic applications. Also, virtual DOM enables faster performance of ReactJS apps than AngularJS apps for the applications of the same size.

  • Dependency Injection
    It is a software design pattern that helps in making components reusable, maintainable, and testable. AngularJS automatically finds the appropriate injected objects with parameters such as $routeParams, $filter, store, and $scope. $inject and $provide are the two functions that make dependency injection possible in the AngularJS framework. However, the built-in container for dependency injection with React is missing. It is made possible by the inclusion of instrument modules, such as Browserify, RequireJS, ECMAScript 6 modules. It is one of the significant points of comparison between AngularJS and ReactJS.
  • Directives And Templates
    AngularJS has its directives to work on DOM. ng-bind or ng-app are some of the standard directives with Angular JS. Further, you can even create your directives as well. It is considered as one of the most powerful ways to work with the Dom. Also, to summarize, we can use directives, both standard and specific to bind DOM elements with AngularJS applications.React does not offer any division into templates and directives or template logic. The template logic is required to be written in the template itself. React chooses to reinterpret all templates and the UI every time an event occurs.
  • Scalability
    With its intuitive design and powerful CLI, Angular is easy to scale. React is testable and therefore scalable compared to other frameworks like Vue.js.


Conclusion: Which Is Better ReactJS or AngularJS?

In summary, AngularJS and ReactJS each have great support from their community and offer strong documentation although they have different philosophies on how application development is addressed.

Considering all the features mentioned above, we have tried to highlight the difference between React JS and Angular JS, though it is a hard choice to declare a clear winner as each one of them are good at what they do. Therefore, you should,

Choose ReactJS for your project if:

  • You plan to expand the functionality of your application in the future
  • You have dynamic content that changes your views or needs an app that will update the look simultaneously and constantly
  • You agree with a slower initial phase of development

Choose AngularJS for your project if:

  • You are in the inception phase of development. Also, if you wish to start application development, and require a holistic framework that will get you started quickly
  • Seeking a robust and well-maintained framework for the project-range of any size

In short, if you are looking for flexibility and simplicity, it is better to use React.js. However, if you need the most efficient way to organize and boost your application with a complete tool, AngularJS remains your best solution.
