Angular vs. React: Which is Most suitable for Your Web Application?


Though JavaScript is one of the most famous and preferred languages for front-end application development, developers face a dilemma when choosing the proper framework or library for their app development projects. 

Angular and React are two names that pop up when we think of the JavaScript ecosystem. Both are highly popular, and developers love them as well. Both front-end development frameworks offer some unmatched advantages to developers, and at the same time, both frameworks have their limitations. 

However, the million-dollar question is: which one to choose for your project? 

For example, developers want to know which one is easy to learn and has higher demand career-wise. Businesses want to know which framework might help have an app that is seamless, feature-rich, and has a superior user experience. 

Should you hire Angular.JS app development services, or should you go for React developers? What are the main differences between these two frameworks? What should be the criteria for choosing Angular and React frameworks? It is like selecting the candidate for voting when both of them are honest, dedicated, and hardworking. 

We have covered almost all aspects of both frameworks to help you make the best decision for your project. Keep reading and get your answer in just a few minutes! 

What is Angular?

Angular or Angular.JS is a decade-old web development framework powered by Google and built on typescript. Being a component-based web application framework with highly integrated libraries and features, Angular.JS has carved a niche for itself by offering highly scalable, feature-rich, and highly functional web apps. 

Some of the most notable features of Android.JS are client-server communication, routing, two-way data binding, dependency injection, etc. 

Another significant point to mention is that Google and constantly updated technology back it. Google just released the Angular 12 update with the latest features and functionalities. Also, Angular.JS has the support of its large community base. In case of any issues or concerns, developers can turn for community support instantly. 

In short, Angular.JS is one of the leading players to remember for web application development.

What are the benefits of Angular.JS?

Two-way Data Binding

Thankfully, developers have no role to play when it comes to data binding.

Angular.JS allows super faster and more accessible data binding, also referred to as two-way data binding. As soon as you make any changes to the view, it will immediately reflect the model and vice-versa.

DOM Manipulation

Furthermore, the two-way data binding also makes it easier for active DOM manipulation. Coding, translating, and updating DOM elements is quicker, faster, and effortless.

Improved Server Performance

The server CPUs performance is excellent as Angular.JS supports caching and other processes, which results in reduced traffic.

Application Prototyping is Faster

Developers can quickly develop highly functional application prototyping with lesser code.

Responsive Web

Angular.JS makes it possible to develop highly responsive, quicker, seamlessly navigating web applications that offer superior user experience and user interface.

Highly Testable Products

Furthermore, features such as dependency injections make it possible to allow various app components to be isolated and tested. Angular.JS allows unit testing and end-to-end testing, which makes testing and debugging more streamlined and straightforward.

The MVVM Architecture

Also, developers can improve the app performance as Angular.JS offers Model-View-Controller and Model-View-View-model architectural patterns.

Use of Directives

With directives, front-end developers can make the scripts and HTMP pages organized and uncluttered. With this benefit, they can also make independent codes and use them repetitively.  

Fast Development

With Angular.JS, you can expect rapid development. Even freshers can learn the Angular.JS framework easily and quickly to make highly functional web applications.

What are the limitations of Angular.JS?

  • Though developers can develop a DOM quickly, the performance of DOM elements might not be as expected.
  • It is challenging to integrate third-party libraries and extensions with Angular.JS.
  • The number of resources to routing is limited for Angular.JS.
  • Sometimes, the debugging might offer you some performance and functionality issues.
  •  The speed of the pages might be slow due to the embedding of pages’ interactive elements.

What is React?

React is another open-source JavaScript library that is mainly used for front-end web application development. Developers can easily create interactive and challenging user interfaces with React, a component-based framework for developing UI components. 

React functions on a simple concept- Learn Once Write Anywhere. It helps developers to create highly scalable web applications in just no time. It is managed by Facebook and has a large community to help developers when they face any issues. 

Facebook developed it in 2013, and since its inception, it has allowed developers to create seamless, highly impressive, and dynamic user interfaces. Hire a React.JS app development services provider for your project.

Developers also use React.JS to develop single-page web applications and mobile applications. Apps developed with React.JS are highly productive, quick, and highly scalable. 

What are the benefits of React?

Easy to learn and use

React is available with lots of documentation, tutorials, and training materials to help developers understand it from scratch. If your developer has a little bit of idea about JavaScript, he will learn to React in no time.

Easy dynamic web application development

Earlier, it was tricky to develop dynamic web applications with HTML strings as it required complex coding. However, with React, developers can create scalable, dynamic web applications with less coding using JSX (JavaScript Extension).

Reusable Components

React.JS app development allows developers to reuse the HTML code of each component of the application. It also makes your app development easy and quick. You can create complex applications with the help of simple building blocks made by these components.

Superior performance

The DOM here is virtual, which improves the app’s performance by dealing with HTML, XML, and XHTML. The real DOM, when updated, is used to slow down the performance. React brought the concept of virtual DOM, which eliminated the performance issue.

Availability of Support Tools

React has several handy tools on its sleeve which make developers comfortable. You can inspect the component hierarchies in the virtual DOM with these Chrome and Firefox dev extensions.

SEO friendly

Generally, search engines find it difficult to read JavaScript-heavy applications. However, with React-powered web applications, you will not see this issue as these applications can run on the server and the virtual DOM makes it possible for the page to render and return to the browser.

Easy to test

Native tools help developers to test React applications quickly and effortlessly.

JavaScript Library

React offers a rich JavaScript library that provides developers superior flexibility and versatility to choose what they want.

What are the limitations of React?

  • Though the development pace is very high, sometimes, developers find it challenging to cope with the constantly changing things. It becomes challenging for them to adopt changes that happen continuously.
  • As the framework is updating so fast, it makes it impossible to document changes properly. Front End Developers have to write instructions on their own to overcome this issue. 
  • It only covers the UI part of the app, and for other factors, you will need other technologies and tools.
  • Though JSX has its benefits, some developers find it a barrier as it is complex to learn and implement.

A comprehensive comparison of Angular and React

So, should you hire React.JS or Angular.JS app development services? Let’s compare Angular and React for some specific aspects to give a clear idea about their differences. 

UI components

React developers create their UI tools for UI components, some of which are free and some paid.

However, when it comes to Angular, it has an in-built Material tech stack with advanced-developed components, which makes UI configuration quick, seamless, and easy.

Real DOM Vs. Virtual DOM

Though Angular’s real DOM has updated tree data structure even when one segment is changed, React.JS has virtual DOM that is easy to ponder and allows developers to track and update changes without affecting the other segments of the tree data structure. Hence, virtual DOM is highly effective here.


The Angular.JS framework depends on three layers- Controller, View, and Model. The Angular.JS structure allows front-end developers to break the app code into different files. It further will enable developers to use element templates repetitively in other parts of the application. 

On the other hand, while developing an app on React, developers can build element trees, making React codes more logical and easy to read than Angular code. Developers don’t have to write code mainly. 


Angular and React use code editing tools such as Visual Studio, Sublime Text, and others. What differentiates both are tools such as Create React App (to bootstrap a new React Project),

Next.JS (for React developers to do server-side rendering),

and Angular CLI (to create a new project in Angular framework), Angular Universal (for server-side rendering for Angular).

The main highlighting thing about Angular is that you can test an Angular.JS application using a single tool such as Jasmine, Protractor, or Karma. Here, Angular wins over React.


React.JS wins here as documentation is more robust and highly organized than Angular.JS, where the documentation is not updated due to the continuous development procedure. If you are looking for a framework with superior documentation, hire React.JS app development services.

Mobile App Development

Angular.JS uses an ionic framework for mobile app development with a UI component library and a Cordova container. The developed app will look like a website in the web application container if you see it on a device.

On the other hand, React.JS mobile apps offer a superior native UI experience to users. Developers can make elements and bind them with the help of the code written in Kotlin, Java, and Objective-C. React wins here.

Productivity and Development Speed

Angular offers superior productivity and quicker development speed due to the CLI that empowers developers to use one-line commands to create elements and services. It also has an in-built procedure for addressing issues.

When it comes to React.JS, third-party libraries impact productivity and speed. In addition to that, the React toolkit also varies from project to project. It means developers have to put more effort and time into updating the app. Angular.JS wins here.


The Stack Overflow Developer Survey 2020 suggests that React is more popular compared to Angular. However, both React and Angular are widespread and growing technologies worldwide.

Freedom and Flexibility

React.JS developers have more freedom and flexibility to choose the architecture, libraries, and tools for web application development. You can create a highly tailored application with React. 

Angular.JS offers limited flexibility and freedom.

Testing and Debugging

You can use one tool such as Karma or Protractor to test the entire Angular application.

It is not possible with React.JS. Here, you will need multiple tools to perform different types of testing. It will require more time and effort.

Data Binding

Developers acknowledge it as one of the most crucial factors in selecting the framework for web app development.

While React.JS uses one-way data binding, which does not allow developers to change the UI components without updating the model state, Angular.JS has a two-way data binding approach that automatically alters the model state when changing the UI component and vice-versa.

Here, Angular and React both are winners as both are effective and offer excellent data overview.

Community support

The 2020 Stack Overflow Developer Survey clearly states that developers working on React projects are higher than developers working on Angular projects. React has much community support compared to Angular.

App Functionality and User Experience

While React uses Fiber and Virtual DOM for app development, the new Angular update features ShadowAPI, which offers brilliant app functionality and user experience. Hence, both are winners in this case.

Learning Curve

Angular wins the race as it has a big learning curve with multiple options to address a specific issue. Furthermore, Angular.JS has a complicated component handling system that asks developers to be familiar with different concepts and programming languages such as pipes, RxJS, Typescript, dependency injection, etc.

On the other hand, you don’t need much expertise when it comes to React app development. You can quickly learn and develop an app in the React framework if you are good with JavaScript.


When the app does not need more functionalities and features and the complexity is not very high, you can go for Angular.JS. Furthermore, you can go for Angular development when looking for superior productivity, and your development team is well-versed with Angular, C#, and Java.


When you need to develop shareable elements in your app with several events, you should use React when you want a tailored app. Also, when your team is good at JavaScript, CSS, and HTML, you can go for React.JS app development services. 


Both, Angular and React are good and have their abilities and issues. Here, developers have an extra task to choose the best suitable framework for your app development project. They need to list down some key highlights of the project and determine which framework can help build an app that serves the core purposes. Also, you can choose a React app development company that also offers Angular.JS app development services. It might help you to keep unwanted issues away during the development phase.
