Angular vs React JS: which one is the best?

Angular vs. React JS: which one is the best?

When it comes to choosing a suitable JavaScript framework for the creation of a high-quality online application, developers have several alternatives. Angular, React, Vue, and other frameworks are among them. However, developers may find it difficult to make a selection because each of these frameworks have their own advantages and disadvantages.

As a result, before deciding on one of them to carry out your job, it is strongly advised that you compare them and determine which one meets your needs best.

When the two big JavaScript frameworks are brought together, it will undoubtedly be an interesting topic to discuss. Experts think that this comparison should be based on a number of factors, including the project's size and budget, the features to be included in the web application, team members' experience, interoperability, and so on. This blog explains the difference between Angular vs ReactJS.

Angular vs. ReactJS: A Quick Comparison

What is Angular?

Angular is a Google-created open-source framework for developing online apps. Angular is built on TypeScript, whereas React is based on JavaScript. And, unlike React, Angular is a full-fledged MVC framework, so you won't need any other solutions after you've mastered it.

The initial version of Angular, AngularJS, was rewritten to create Angular.

Pros of Angular

  • First, developing a customised Document Model Object is easy for developers.
  • You have access to angular libraries, which aid in the creation of robust template solutions.
  • It has the benefit of having an injection subsystem dependency built in.
  • If you want to run a unit test with Angular, you'll need to inject mock data into the controller first, and then inspect the result and its behaviour. You may create each of the individual pages independently and then combine them with the components to view the final product.
  • It has a single routing option and a visually appealing User Interface with data binding.
  • The data between the model view and the component must be synchronised.

Cons of Angular

  • Though developers may easily create a customised Document Model Object (DOM), they may run into issues with the DOM element performance.
  • Because Angular is a difficult pill to chew, learning the ropes can be challenging.
  • It has a restricted number of resources for routing.
  • Debugging may be challenging at times.
  • Because of the interactive components embedded in the sites, it might be sluggish.

What is React JS?

React.js is a free and open-source JavaScript framework for creating fast and appealing user interfaces. It combines the ease of development (due to tiny bits of code known as "components") with a significant emphasis on user experience. React is the View layer of the MVC model, giving you nearly complete control over whatever Model and Controller frameworks you choose.

1. Architecture

One of the most basic areas of comparison is the architecture of technologies, which indicates how they are constructed to work. The same can be said for the ReactJS vs. Angular argument.


The ‘view' part of application development is handled by ReactJS. ReactJS is a UI rendering framework that renders written code (JSX) for every component of your application.

To put it another way, ReactJS is a library of code that you may use to start with the fundamentals of your software applications and easily add and update functionality. It does not impose any restrictions on the architecture of your apps and gives you a lot of flexibility during the development process.


Angular, unlike React, is a full-MVC framework for front-end development, which means it controls the whole architecture of your program. Unlike ReactJS, which allows you to add functionalities to your current websites and apps with ease, Angular provides only a limited amount of flexibility. The application and architecture you create with Angular will be restricted only by the tools and functionalities that Angular provides. As a result, it has a significant impact on the architecture of your product.

2. Document Object Model (DOM)

If you're unsure whether to utilise Angular or React, comparing the Document Object Model (DOM) of the two technologies might help you decide. For those unfamiliar with the DOM, it is a programming interface that demonstrates how a browser reads the objects and nodes in your HTML or XML projects. When comparing ReactJS and Angular, they manage the DOM in entirely different ways.


Is ReactJS losing its popularity?

ReactJS runs on a virtual DOM, allowing it to be extremely fast. It is a unique feature of ReactJS that has helped it become so popular. ReactJS' programming interface works with two snapshots of your HTML content since it has a virtual DOM. The first is an original snapshot, while the second has your modified modifications.

It can identify the change in your code when comparing the two snapshots and practically implements it without rewriting the full HTML content. As a result, the application gets a huge performance gain because it doesn't force the entire browser to redraw itself every time something changes.


In contrast to React's virtual DOM, Angular provides a normal DOM that does not instantly recognise changes in a file to update the newly made modifications. Rather, every time a new modification is made, it changes the entire HTML structure. The application's performance suffers as a result of the continuous updates, and the user experience suffers as a result.

3. Templates

Angular JS and React JS, like other programming tools, employ a variety of templates.


ReactJS uses a template called JSX (JavaScript XML), which combines JavaScript and markup into a single line of code to quickly construct user interfaces. JavaScript has a feature called JSX. It has an HTML-like syntax and allows you to combine code and markup to create components.

Angular, on the other hand, uses templates based on advanced HTML. This implies that in order to create code in Angular, you'll need to understand the appropriate HTML syntax. With Angular, you may build in-line templates or utilise template URLs for external templates.The syntax of Angular directives is complicated and sophisticated, which might be a big disadvantage for someone who has never worked with this technology before.

4. Components

Components are pre-written code components that make adding functions more convenient. Because ReactJS and Angular both use a component-based architecture, they are the most significant. However, there are some marked differences between ReactJS and Angular.


ReactJS is a component construction and rendering library. It has a number of free and premium UI components that you can use to quickly add features to your project. Aside from that, JavaScript may be used to create similar components.

ReactJS' component-based approach has the benefit of having community-developed UI tools, and its React site is a wonderful resource. You may utilise a variety of free and premium UI components on the React site.


Angular, unlike React, is not just about components. It is a full framework or platform with a comprehensive tool suite to enable you to quickly create contemporary, reactive, and component-driven apps, despite the fact that it follows a component-based strategy. This means it has additional solutions that allow you to quickly design components like routing, state management, form validations, and other tools needed to build huge applications.

5. Data Binding

The differences in data binding are at the heart of the ReactJS vs. Angular discussion, and they may be summarised as a "one-way binding vs. two-way binding" discussion.


One-way data binding is supported by ReactJS. Data travels in one direction when the Model and View are synchronised. To put it another way, changes to the Model state are only reflected in the View (i.e., the user interface) of the application when you update it.

Changing the UI element, on the other hand, has no effect on the Model state. As a result, data only travels in one direction: from the model state to the user interface.


Angular's data binding model, on the other hand, is bi-directional, which means that data flows in both directions between the Model and the View. Angular, unlike ReactJS, synchronises the Model and View whenever the model state and/or the user interface are changed.When you alter the Model state, the UI changes, and when you update the UI, the Model state changes.

6. Performance
Is Angular faster than React?

When deciding on a front-end development technology, developers must consider how their choice will affect the application's performance.

Let's have a look at the differences between ReactJS and Angular and see how they compare in terms of the performance of apps developed with these frameworks.


Both ReactJS and Angular are well-known front-end development technologies that are equally capable of building large-scale apps. So, why use React rather than using Angular? 

Developers all across the globe believe that ReactJS and Angular are vastly different due to ReactJS' ability to ensure excellent speed. ReactJS' virtual DOM functionality allows its applications to update changes without having to rewrite the full HTML document. This allows for considerably faster updates, resulting in lightning-fast performance regardless of the application's size. 


Angular is a complete front-end development framework; however, its regular DOM functionality slows down the application, especially when compared to ReactJS-based apps.

As a result, Angular is best suited to creating single-page applications (SPAs) that only change one view at a time. With large, sophisticated, multi-faceted applications, it provides poorer performance. Angular optimises speed via the change detection method.

7. Scalability

When deciding between Angular JS and React JS, keep the project's future scope in mind. In today's ever-changing environment, creating scalable apps that can readily adapt to changes in the size of the user base and services they provide is critical. Developers are looking for front-end development solutions that will allow them to grow their applications quickly in the future if and when needed.


ReactJS, as a frontend library, contributes relatively little to the development of scalable apps. Does this imply that React-based apps aren't scalable? No. It implies that scaling React apps necessitates the use of third-party technologies and connectors not provided by ReactJS.


Angular comprises more than simply component building: it also includes routing, state management, HTTPS, and other features that aid in the development of large-scale projects. If you need to grow an existing application by adding functionality, Angular has all of the essential capabilities. As a result, Angular is a top choice for building scalable software solutions.

8. Learning Curve and Development Experience

When picking from a number of accessible alternatives, developers should consider the learning curve of a new technology as well as the amount of development expertise it demands. Especially, if you're a newbie who's just getting started with front-end programming.

So, if you're asking yourself, "Should I study React or Angular?" For you, the learning curve and development experience are critical benchmarks.


When it comes to understanding the learning curves of both ReactJS and Angular, the ‘Library vs Framework' argument becomes crucial. Because ReactJS is only a library, it has a shorter learning curve and does not need the mastery of a large number of technical ideas.

Furthermore, ReactJS makes use of JSX (Javascript XML), which is quite simple to pick up if you've worked with Javascript before. Its HTML-like syntax may need some time to become familiar with, but once you get the hang of it, everything else is easy.


Since Angular is a comprehensive framework with numerous tools and solutions built in, learning to use it is a high learning curve. As a starter, you'll need to learn how to use the Typescript language that Angular employs.

You'll also need to learn about all of Angular's rich subjects, which range from components, templates, modules, and other fundamental ideas to more advanced concepts like dependency injections, change detection, and RxJS. The sheer amount of information needed of newbies might be intimidating.

Angular vs ReactJS: When should you use each of them?
When should you use Angular?
  • The app's complexity remains low to medium.
  • You require ready-made solutions as well as increased productivity.
  • The development team has worked with Angular, C#, and Java in previous editions.
  • You'll need large-scale software with a lot of features.

React js vs angular which sohoul one use

When should you use React?
  • Your app development staff knows JavaScript, CSS, and HTML inside and out.
  • In your app project, you must include shared components.
  • You require a tailored app solution.
  • You'll require an app with many events.

Both React and Angular are excellent app development technologies. These two frameworks have a lot of advantages; however, React works better than Angular. It is more widely used, stays fashionable, and continues to expand. Furthermore, ReactJS has a sizable developer community behind it.

Because it runs virtual DOM and displays optimizations, React defeats Angular. It's also simple to switch between the React versions. Unlike Angular, you don't have to install updates one by one. Finally, React provides a variety of options for developers, allowing them to decrease the development time and mistakes.

Both Angular and React depend on your need for usability and functionality. Angular is a complete framework, whereas React is a library rather than a framework. Reactjs requires less coding, and when compared to Angular in terms of speed, it is clear that React is much superior to Angular.


1. Is Angular better than React?

Because of its virtual DOM implementation and rendering improvements, React outperforms Angular. It's also simple to switch between React versions; unlike Angular, you don't have to install updates one by one. Finally, using React, developers have access to a wide range of pre-built solutions.

2. Is React faster than Angular?

No.Most developers and decision-makers assume that ReactJS provides considerably greater performance and speed than competing frameworks like AngularJS and EmberJS.

3. Why react JS is better than Angular JS?

Due to its superior Virtual DOM features, extensive community support, abundant documentation, light-weight characteristics, reasonable learning curve, and flexibility to provide mobile functionality with React Native's, React JS is better than Angular or Vue JS.

4. Does Google use Angular React?

Yes! Internally, Google uses Angular for all of its official websites and applications. A few Angular sceptics frequently point out that none of Google's leading apps, such as Gmail, are written in Angular. Gmail has been available since 2004, while AngularJs was created in 2009.

5. Which is more powerful Angular or React?

React is presently more widely used by developers than Angular, according to its 2020 version (35.9% vs 25.1%). Additionally, React is a more popular (68.9% vs. 54.0%) and wanted (22.4% vs. 10.6% ) technology among developers.

6. Can I learn React without knowing JavaScript?

React is a JS library, it is impossible to avoid knowing JavaScript. You can't learn React without JavaScript, or without even knowing what JavaScript is. React makes extensive use of JavaScript in compared to other frontend technologies.
