Angular.js Vs React.js: Which Framework Is Better?

JavaScript is one of the most widely used languages for web development and most popular websites use it as their web framework. Among all its frameworks, Angular.js and React.js are the most popular ones in JavaScript.

In this article, we will showcase the top comparison points between the two:

1. Architecture

Angular.js is based on the model-view-view-model (MVVM). It has a lot of in-built tools like data link, change detection, forms, routing, navigation, HTTP implementation, and many others. React.js only has the model-view-control (MVC) model. It does not have many built-in tools and the user has to use other libraries like Redux and Flux as a controller or react-router for navigation.

RESULT: Angular.js wins

2. Simplicity

Angular.js It is a full-fledged framework that can run in any platform or browser. It has many inbuilt tools and is much more mature than React.js.

RESULT: Angular.js wins

3. Performance

React.js is not a full-scale framework. Integration of the UI library into a common MVC framework requires deeper programming knowledge. Angular.js turn towards the external sources, which delivers higher performance to the Angular mobile applications. Its MVVM reduces the loading speed of the web pages considerably compared to React.js. It has a visual interface on the client side and hence part of the back-end queries is removed, thereby increasing the speed.

RESULT: React.js wins

4. Scalability

Angular.js is very easy in terms of scalability because of the design that it has and a powerfulCLI. React.js is scalable compared to other frameworks.

RESULT: Angular.js wins

5. Resolving Dependencies

Dependency Injection (DI) is a software design pattern that deals with how components get hold of their dependencies. The Angular.js injector subsystem is in charge of creating components, resolving their dependencies, and providing them to other components as requested. It lets the user write dependencies in a separate file. React.js does not offer any DI. But there are many instruments to inject dependencies automatically in a react application. Instruments such as Browserify, RequireJS, EcmaScript 6 modules which we can use via Babel, ReactJS-di and many more.

RESULT: Angular.js wins

6. Model Complexity

Large models cannot be used in similar apps because it is sensitive in terms of scope. Although it does make the code look simpler the programmer would then need to break down sections and rebuild it again. On the other hand, React.js gives the option to choose.

RESULT: React.js wins

7. Faster Testing

React.js extensively uses Redux, which is a predictable state container for JavaScript apps. It makes easy management of the data that is displayed and how one responds to user actions. This cuts down the extra work of storing and managing component states in large-sized, complex applications that have dynamic elements. Every component can then access the application state without involving the child components. This makes it easier to test the application and log data changes, along with the use of hot reloading and other such tools.

RESULT: React.js wins

8. Error handling

Angular.js has some unique error handling features like an upgraded error handling process for output in the scenarios where a property is not initialized. React.js does not have such a convenience in error handling.

RESULT: Angular.js wins

9. Community support

Angular.js is supported by Google and has vast community support. A large number of developers contribute to the community every day. React, on the other hand, does not have that much of community support. Taking into account the number of tutorials and ecosystem that it has, it is still young and not very mature.

RESULT: Angular.js wins


Angular.js is a framework, whereas React.js is more of a library. Despite both the frameworks have a large number of differences, they both can still be used to create similar apps. The project would decide what framework of JavaScript is best suited, according to the requirements. Both have a wide set of tools suitable for web applications.
