Angular or React: Make your choice right with the JS frameworks

Angular or React

Choosing the right JavaScript frameworks often stirs up confusion because options are aplenty to meet the project requirements. Here the crux lies in opting for the right one matching your project requirements. For that, you should be well aware of the crucial aspects of these frameworks. We have tried to make a fair comparison of Angular Vs React to help you make the right decision.

What is Angular?

Angular is a front-end web application framework. It was known as Angular JS when it was first introduced in 2000 and became one of the most popular web development JS frameworks. In addition to the support of a tech giant, its features such as two-way data binding and dependency injection turned out to be the core reasons behind its popularity.

It has tools and components with unified libraries and features to develop and scale projects to enterprise-level applications. Besides, the Angular team at Google constantly updates it with the latest technology. Angular 9 is the revised version of Angular which was released in February 2020. It has got an update with TypeScript 3.6 and 3.7.

What is React?

React could be best described as an open-source JS library for front-end development supported by Facebook. It helps developers to build highly interactive, dynamic, and versatile User Interface with the help of component-based architecture. React is also used to create mobile apps and Single Page Applications. Irrespective of platforms, it also helps developers to make apps that are highly scalable and speedy.

Angular Vs React: Detailed Comparison

Framework Vs Library

While Angular is a framework, React is a library. Since Angular is a full-fledged framework, it does not need additional libraries as its various functions like component-based routing, dependency injection, data binding, project generation, and form validation could be managed by Angular itself. Its inbuilt small libraries are immensely helpful to build complex apps.

As mentioned earlier, react is a library, and the apps written with React demand additional libraries. Thus, react offers more freedom to structure code as the case may be.


The language in Angular is based on TypeScript, a subset of JS, and is a statically typed language. Anyway, developers have to be comfortable with TypeScript before using Angular.

React relies on JS, a dynamically typed programming language. Here you need not define the variable’s type and easy to use.

Data Binding

Data Binding implemented by Angular is two-sided in which a modification in a UI element can influence the corresponding model. Likewise, if you make any modification to the model state, then the UI element would also follow it.

Whereas, React uses one-way binding in which the model state is updated initially, and the change is shown in the UI element at the end.

Even though Angular approach of two-way data binding is considered to be easier at the initial stage, React is the better option if the project grows larger. Because it helps to debug easily.


Angular uses regular DOM which causes comparatively potential performance issues. But react has the capability of boosting performance compared to Angular because of its use of Virtual DOM trees.

As Angular uses a two-way data binding process, each binding demands a watcher to keep track of changes and each loop does not proceed till all the watchers are confirmed. It makes a lag in performance.

But with React, it happens contrary to that. Since it is a one-way binding process, binding is not assigned to watchers and their workload gets reduced.

DOM (Document Object Model)

Regarding the use of DOM in Angular, if one part of DOM is modified, the entire tree data structure would be updated.

However, React use Virtual DOM that allows developers to track and update changes to the VDOM selectively without affecting a section other than the intended one. Besides, VDOM is ahead in performance than DOM and that is a better option for app development.


Compared to react, Angular has a variety of features. React mostly depends on a state management library. So, in that way, it can optimize the state management processes, interaction with the API and routing with the help of libraries like Hemet, Redux and Router.

However, Angular does not need additional libraries and it integrates multiple functions in its package. But it is also possible to use state management libraries to improvise its features.

How To Decide If Angular or React App Development Is the Right Choice for You

Indeed, React may offer plenty of features and benefits. But the thing is whether your team is equipped with the framework to take on React app development. Try to look out for the below-mentioned things in your team and you can make the right choice for you.

  • Your team should be well-versed in using HTML, CSS, and JavaScript.
  • Your project demands a highly customized app solution.
  • The developers are in need of various features and variable states in the process of development.
  • The project is in need of sharing various components that is required to be shared across a number of apps.

For Angular app development, try to look out for these things in your team before your decision on the choice. 

  • Team expertise and experience in C#, Java and earlier versions of Angular.
  • Angular is apt for low medium complexity apps.
  • If you look for ready to use solutions and high productivity.
  • In case your team requires to rely on Bundle Budgets through the CLI option, Angular is the right choice.

Wrap Up

Given so many frameworks at your disposal, each one having their own unique features, choosing the right one is not an easy task.

There is no doubt that both Angular and React, are powerful technologies and have many advantages in terms of improving, facilitating, and quicker development.

While Angular has many inbuilt functionalities, React has a simple learning curve which helps for faster development.

If you look for an enterprise-level application, it is better to choose Angular as a bigger learning curve is not a barrier for them. But React stands to be a good choice to create an app from an easy learning curve.

Anyhow, deciding between Angular and React has to be based on personal preference and as per the requirement of your entity. Because both find solutions for the problems in their own way.
