      • When You need to create sharable components on your web application
      • When you want a personalized app solution


Angular vs React – The Complete Comparison


      • Angular is a structural JavaScript framework built using Typescript, whereas React is a JavaScript library created using JSX – JavaScript XML.
      • Developers mainly use Angular to build complex enterprise-grade apps like single page applications and progressive web apps. In contrast, React is used to make UI components in any app with frequently variable data.
      • Angular’s learning curve is sharper because of its many in-built functionalities while React’s smaller package size.
      • Angular offers testing and debugging for a complete project with a single tool, while to do different types of testing, React needs a set of tools.
      • Angular doesn’t add the JavaScript library to the source code, while React adds the javascript library to the source code.
      • One of the most significant differences extends in state management. Angular comes with data-binding bundled in it. On the other hand, React is usually improved by Redux to offer unidirectional data flow and work with unlimited data.

These and some other distinct features make Angular and React fundamentally different. So, let’s understand the technical specifications first with the help of the information given below.

Top Brands Using Angular and React


Here is what I have learned:

Choose React for your project


      • You have a plan to increase the functionality of your upcoming web application.
      • Your project has dynamic content that changes your views or needs an app to update the design simultaneously and constantly
      • You settle down with a slower initial phase of development.


Choose Angular for your project

if :

      •  You are also within the beginning phase of development if you would like to start application development and need a holistic framework to get you started quickly.
      •   Seeking a well-maintained and robust framework for the project varies of any size.


What is Angular Good for

The front end development becomes faster with angular. It is also known as the standalone solution for creating the quickest data-driven web applications. Moreover, since Google developers make it, you have surety of its reliability and efficiency of code backed up by the vast community of tech experts.

In addition, Angular has recognized its model-view-controller (MVC) capability that enhances the functionalities of browser-based applications by reducing the JavaScript code required to keep the application functional and robust. Angular is one of the most popular frameworks to build mobile apps. Angular offers a lot of stuff “out of the box”.

Reasons for Choosing Angular :

      • Inbuilt features of angular such as Rxjs, AngularCLI are more powerful to make channels of exchanging info and in independent event handling. Creating apps, adding files, and debugging a project is hassle-free while using Angular.
      • It overall improves the developers’ efforts and reduces lines of code by parallelly running the components.
      • It Raises the overall performance.
      • It makes a speedy rendering of server-side, supporting the views that lack browser-side rendering.


Angular Use Cases:


Paypal is the largest and one of the most ordinarily used payment gateways in the world. It has used Angular to create the PayPal checkout system that contains essential features such as a payment review page and adding MasterCard pages. These options bring a high level of security issues on the side of smooth functionalities as primary needs.


Upwork is that the preferred platform for freelancers has quite ten million freelancers who use Angular. For extremely functional platforms like Upwork, it’s necessary to use technologies like Angular to keep up the functionalities smoothly and replicate the changes within a fraction of seconds.


Localytics is one of the world-famous tools utilized by well-liked names like Microsoft, The New York Times, HBO, and more. It uses Angular to boost its features and place itself into the standalone identity by using the UI suite of Angular. With success, it cut back the amount of code required to keep the application functional.


What is Reactjs Good for

Reactjs is an open-source library. It handles the application’s view layer, and developers choose to build reusable UI components. It is swift and scalable to change the data without reloading the page on the browser. Reactjs used on Facebook.

First, and later Instagram has implemented it in the news feed. However, mainly the big-scale applications are using Reactjs for loading the data without refreshing the pages.

Reasons to use React in the web application:

      • Different from Angular, developers compelled to integrate external entities to access specific functions of React and gain the interactive functionalities
      • It has state containers such as redux for faster development in scalable applications, for example, using the dynamic components and managing rendering on the server side.
      • Converting JSX into JavaScript for browser understanding
      • The requirement to use code bundlers like web pack
      • Need to Use the URL router library of React like ReactRouter

React Use Cases: How good it is


Netflix is an excellent media streaming platform, using React specifically for low-performance devices. Additionally, Netflix uses the Reactjs library to boost runtime performance, modularization and increase start-up speed.

The New York Times:

The New York Times has additionally designed the latest project designed for celebrities’ completely different appearances on the Oscar red carpet. The project was engineered using the Reactjs platform and let the users apply filters and find pictures of their selection. Reactjs has made it possible to fully re-render and stood out as the most impressive feature of the framework.

Performance in Angular and React

React Performance

React’s performance has dramatically improved after introducing the virtual DOM in the framework.

Meanwhile, all virtual DOM trees are lightweight and designed on a server, reducing the load on the browser. Furthermore, since the data-binding method is unidirectional, bindings aren’t allotted to watchers as Angular. So, exclusively, It does not create other workloads.

Angular Performance

Angular performs worse, particularly in the case of complicated and dynamic web applications. The performance of Angular apps is negatively suffering from bidirectional data-binding. A watcher is allotted by each binding to trace changes. Each loop continues till all the watchers, and associated values are checked.

As a result of this, the additional bindings you have got, the other watchers are created, and the cumbersome process becomes. However, the major recent update of Angular has dramatically improved its performance, and it doesn’t lose to React any longer.

Also, the size of an Angular application is somewhat smaller than the size of a React app.

Testing in Angular & React

Angular Testing

Testing in a dynamically written language like Javascript makes it tough to realize 100% testing goals. That’s the reason why code written in Javascript must come back up with a robust set of tests. On the other hand, Angular has multiple features like isolation of the coding unit and is written with all the issues relating to testability in mind.

For instance, the in-built Angular feature, i.e., dependency injection, makes it straightforward to pass in dependencies of elements and mock the components.

React Testing

While writing tests, mocking the components that don’t seem to be already existing within the testing environments is preferred. Tests will spy on the other parts of the function and predict their interactions with them.

It’s the mocking of data or functionality, and it’s pretty helpful to avoid flakiness in data fetching. Tests are substantially predictable in Reactjs because of the supply of mocking functions.

As a part of the development process, Reactjs executes test suites continuously to run the test cases. It also offers test runners like Mocha, Ava, and Jest capable of running tests whereas already running the development process.

Since Jest is widely compatible with totally different features like mocked modules, timers, and Jsdm support, at an equivalent time, libraries like Mocha are consistent with the browser-specific requirements and support the simulations like a real browser.

Code Quality: Angular or React?

Angular Code Quality

We can use some specific tools like AngularCLI to boost the quality of code that also brings standards in Angular development. It gives incredible integrations across the project. Integrations like Angular Core, Angular material, etc., can make project deliveries easy and maintain the code quality.

Angular is allowing developers to predict compilation behavior, and also AngularCLI has reduced the learning curve of Angular.

Because of this, it is possible to generate smooth builds and reduce the iterating efforts of developers, which leads to bad code quality in the end.

React Code Quality

Reactjs has plenty of things that not simply increase its code quality but provide an identity that’s completely different from all other frameworks.

For example, using the DisplayName string to debug the messages can distinguish the components.  We tend to use prop-types to check whether or not the prop type is present in the run time.

Maintaining a code quality in Reactjs is simple due to the code review practices it permits by providing Linters. It helps in generating identical coding practices among the developers in a corporation. Later Linters follow a strict set of rules that keep the codebase consistent.

Server Rendering in Angular vs React


Angular is helping the web crawlers by generating static versions of the application that are pleasant and searchable. Angular renders the application by making a static view before it gets interactive using server-side rendering.

It depends on you how skillfully you utilize the combination of JSON and client-side caching to boost the server-side performance. Nothing hits Angular once it comes to reducing the traffic between client and server.
The structure of Angular is in a pattern that has in-built testing requirements like dependency injection and mocking the objects. We cannot doubt its future improvements since Angular has Google as a backup. And it’s capable of reducing the amount of code by eliminating the requirement to recompile and quickly reflecting the front end changes.


If you want to make your application SEO strong, you need to render the application to the server. Reactjs does it quickly with the help of some specific functions. Instead of calling Render, You can do it by calling the RenderToString function.

Unlike other javascript frameworks, Reactjs is a flexible library that would not restrict you from getting benefits. Otherwise, if you want to avoid creating DOM attributes such as data-react-id, you can also use renderToStaticMarkup, which helps create a simple static page generator.

Facebook is the most prominent example of the Reactjs application.

      • Super high-speed rendering
      • Better functions even at the average internet connection

Let’s look at another example of “Dropbox.”

      •  Well-known for online file hosting platform
      • Even and speedy synchronization of data in the cloud
      • Remote connectivity


Two-way Data Binding Availability

Angular Data Binding

Angular uses two-way data binding, and that’s why there’s no doubt that any tech stack will beat the synchronization between two different components as Angular will. It keeps updating the two layers with similar data because the value changes in the input that will update the model layer.

It will bind the HTML element to the model variable. Thus, it is not just displaying it but also changing it in the backend. It facilitates the coordination of the two different data models of a framework. That will help make an interactive user interface without several call-backs and extra efforts by the developers.
Two Way Data Binding
For essential ERP-based software packages like medical software packages, accounting, and other extremely advanced software system requirements, two-way data binding is the most effective technique for fetching the data.

The bidirectional nature of Angular makes it simple to create enterprise resource designing software.

React Data Binding

Reactjs being a library framework, out of the box doesn’t follow the automated approach to data binding and continues its most straightforward however solid architecture. It doesn’t let developers fall into the essence of the complicated handling of objects.

However, Reactjs uses one-way data binding with the two-way data binding helpers to manage each significant parsing work and intensive data manipulation.


Learning Curve – Reactjs and Angular


Angular has a steep learning curve comparison with React. The Google Angular IO framework provides multiple ways to solve a specific problem, has an advanced component management system, yet demands familiarity with totally different concepts and languages like templates, pipes, dependency injection, RxJS, TypeScript, etc. Besides, the framework is constantly developing – making it necessary for the developers to look into what is new-fangled in the Angular ecosystem and upgrade their skills accordingly.

I recommend you choose any of the tech stacks supporting the requirement of your approaching projects. Angular is winning the ground once it involves solving the toughest of the issues in large-scale applications.


Reactjs lets you learn and build an app in the React system if you’re smart with JavaScript. The foremost basic and first things to learn in Reactjs are writing components, managing internal states, and using props for configuration. React is not using dependency injection. It has a Dependency injection system built in JSON.

In addition, ReactJS provides a lot of helpful resources for newcomers to know the framework and look forward to developing a web application, even when frequent extended updates. That is often the number key reason why developers tend to choose React.


Ease of update – Reactjs and Angular


Angular comes with an improved command-line interface that consists of commands like ng update that makes the up-gradation of the app to the newest Angular version easier and quicker. Because of this, Angular development is less painful. Also, it’s necessary to notice that almost all of the updating process is automated, making it further easier.


React additionally offers developers to create smooth transitions from one version to the other. However, front-end development libraries heavily depend on external libraries that make it possible to update and migrate to third-party components. In addition, developers even have to check if the third-party libraries that they need to use are compatible with newer versions of the JavaScript framework or not.




Developers are pretty intelligent when it comes to Angular as compared to React. It’s mainly because of Angular’s unpopularity due to Angular 1.0, where developers had dismissed the framework as too tricky since it needed loads of your time for learning. However, Google has developed Angular that provides constant improvements and long-term support for the framework. As a result, names like Nike, HBO, Forbes, Apple, AT&T, Microsoft, etc., have used Angular.


React contains a broader community as compared to Angular on each GitLab and GitHub. However, as per the StackOverflow Developer Survey of 2018, more developers work with Angular than React. Working with React demands a developer to learn because the framework gets updated very often endlessly.

Although the community will use its best to move forward with the newest documentation, it’s not always that simple to stay up with the frequent changes. React is used by huge players like PayPal, Facebook, Twitter, Airbnb, Netflix, etc. Because of this, the problem of lack of documentation arises quite often.

Each of these technologies has such a lot to offer in terms of features, tools, and performance, making it confusing for development groups to decide on one over the other. To make it simple, we’ve listed some of the queries here that are commonly asked and may guide you in making the correct choice.


Is Angular higher than React?

Angular is better than React if your application is enterprise-grade and you wish to include advanced functionalities like progressive, single page applications, and native web apps. However, React focuses on making UI components and might be utilized in any application, together with single page applications.

Angular uses actual DOM implementation in terms of rendering pages but contains a unique change detection mechanism combined with zones that make web applications faster.

In contrast, React has a virtual DOM implementation that makes refreshing data faster in websites. As a result, each framework has distinct abilities to create high-performing web applications.


How is Angular different from React?

Angular may be a structural, full-fledged framework for building mobile and desktop web apps, whereas React may be a JavaScript library for making interactive and complicated user interfaces. In addition, Angular has a steeper learning curve.

Thus it takes longer initially, whereas React has a shorter learning curve because of its simple structure and small package size.



In the end, we’ve to come back to the point where we will choose any one technology. Given so many frameworks to decide on from, each with its peculiarities, deciding for the proper framework will become a tricky mission.

When we’re between Angular or React, I feel it primarily comes down to personal preference, as they solve similar problems, however, with completely different implementations.

However, in the decision-making process, it’s necessary to consider that React has an easier learning curve that results in faster development, whereas Angular has more inbuilt functionalities.

Both technologies are powerful, a clear improvement from the early days of web development that enhances, facilitates, and accelerates growth.

In this article, I talked about Angular vs React based on a web app we developed from scratch, using each framework.
