What’s the Difference Between Angular and React JS?

Angular and React JS are two widely utilised tools for developing responsive mobile applications. Nonetheless, it is crucial to bear in mind that Angular is a framework, whereas React JS is a library, so matching them against each other is not a valid comparison. In any case, both can deliver the same intended outcome, albeit utilising unique techniques.

Angular is categorised as a framework while React is classified as a library. React solely concentrates on user interface whereas, Angular follows the Model-View-Controller (MVC) blueprint, offering simultaneous access to all three layers of development.

Introduction to Angular

Angular, developed by Google, continues to be one of the most sought-after Javascript frameworks in use and is often labelled as a framework instead of a library. It is purpose-built to render webpages optimally within a web browser.

The support for TypeScript provided by this framework provides programmers with a level of security akin to that of C# and Java developers. TypeScript is an extension of JavaScript programming language that was initially developed by Microsoft.

In accordance with the Apache License, the codebase could be accessible on GitHub. Defining types for a variable, function argument, or output using Typescript is a widely adopted practice.

Concise Introduction to React JS

React JS, developed by Facebook, is a well-established JavaScript library that boasts a devoted community of developers and users. It provides a streamlined approach to displaying the different elements of a website’s user interface (web framework). Hierarchies of components can be presented elegantly and the component structure can be depicted by utilising HTML tags.

As a result, it is primarily accountable for the visual representation and user input. React JS package is typically the starting point for single-page web applications, though it can also be rendered on the server beforehand utilizing Node.js.

ComponentsIts rapid and easy customization of the user interface is due in large part to its integrated toolkit including all components.Community-installed components; further library installation required following a tedious set up process.
Acceleration of ProgressWhile Angular makes developing web applications faster, the time it takes to do either relies heavily on the complexity of the project.Structures are easy to quantify.
FlexibilityWeb applications, either single or multi-page, are possible to create. mobile app development is an Ionic framework dependency.Constructs single- or multi-page web applications. Apps created using the Cordova framework

Relative Popularity Comparison of Angular vs React

According to the 2023 Stack Overflow survey, React emerged as the most popular framework with a usage of 40.14% and an interest of 25.12%, while Angular ranked fourth in terms of popularity (22.96%) and demand (8%).

To obtain an understanding of the frequency of searches for a particular tool over time and the prevalence of different application development environments, Google Trends can be consulted. On this platform, the average monthly searches for Angular are 68, whereas for React, the number is 84.

When considering the significance of total requests, raw downloads are just as important. As per the recent data from NPM, React is seven times more commonly downloaded than Angular.

Taking these three metrics into account, it is evident that React is the favoured framework over Angular.

Jasmine is a widely used option amongst developers who use Angular for generating tests and assertions. Although it is favoured by many professionals, some criticisms have been levelled against it regarding its complexity and the difficulty of understanding its output.


Angular provides a well-structured framework that simplifies the process of modifying and reusing code. On the other hand, React adopts a flexible architecture that is also simple for users to learn.

Angular’s structure is more intricate but stable, whereas React’s approach is straightforward but versatile as it employs novel libraries when generating layers of code dynamically.

The Angular Community

As a result of its widespread application, the React community is considerably larger. A number of major corporations, including PayPal, Twitter, Facebook, Netflix, Uber, Microsoft, and Yahoo have adopted it.

The size of the user base is another advantage of platforms that receive frequent updates, such as React. Although there is not an abundance of documentation that outlines its latest developments, the support offered by specialised forums helps to address this issue.

Due to the initial distrust of developers and the perceived challenge of using it, the user base of the Angular framework has considerably decreased.

The framework’s credibility is bolstered by Google’s support and the fact that numerous prominent companies, such as HBO, McDonald’s, Apple, Adobe, Forbes, Nike, and Microsoft, employ it.


By contrast, the React library has a size of 116KB, whereas an Angular package can range from 500KB. It is advised to opt for React when developing applications that may require expansion in the future.

Although React seems to have several benefits over Angular, is it reasonable to keep using Angular? It’s worth noting that Angular is the ideal choice for designing lightweight single-page web applications.

The Angular vs React Challenge

Once you comprehend the principal aspects of a specific framework, you will be able to draw a conclusion. Learning Angular requires an understanding of TypeScript and Model-View-Controller, which can lengthen the duration of the process.

React doesn’t demand prior expertise and avoids intricate structures and conventional practices. The accompanying tutorial ensures that learning React is a pleasurable experience.

Enhancements and Migration

When the update is released, it will be necessary to make certain modifications to your code. As a result, it’s crucial for developers to check for any updated changes to guarantee a successful upgrade.

React’s custom migration scripts enable users to modify their code with ease. It is advisable to upgrade Angular every six months to maintain any enhancements.

Distinguishing Angular and React by Their Components

Angular’s all-in-one toolkit comprises various UI components, such as layouts, pop-ups, buttons, indicators, and others, facilitating the development of components and frameworks using the inverse technique. This methodology streamlines the task of making interface alterations tailored to individual users.

The React Community takes care of all React tools (free and commercial) on the React website, from production to distribution. To use these tools, a distinct library must be installed, followed by complex interface configuration through React.

Time Taken for Development

The speed at which something is developed depends on the developer’s access to libraries, and each instrument has its own unique advantages in this regard.

React’s architecture is more quantifiable, while Angular provides a swifter and simpler approach to building web applications. Ultimately, the optimal choice for your project will be determined by your priorities.


Both frameworks enable the creation of single- and multi-page applications. In either scenario, mobile programming can be accomplished by integrating complementary technologies like React Native and NativeScript.

Although both frameworks can be employed to develop mobile applications, they heavily rely on third-party mobile application development tools (Cordova for React and Ionic for Angular).

Companies That Utilize Angular and React

Final Thoughts: Angular vs React – Which One Should You Choose?

When evaluating them side by side, neither React nor Angular comes out on top. Both are equally popular frameworks, each with its own merits and demerits, as demonstrated in this comparison.

Angular is a versatile technology that can be employed for both web and mobile application development, while React is mainly intended for UI development and necessitates extra libraries to unleash its complete potential.

Determining whether React can replace Angular ultimately hinges on the type of project in question. React’s emphasis on front-end development, along with its ability to work with other applications, makes it an excellent pick for projects that necessitate a large number of interactive User Interface (UI) elements or heavily rely on them.

Angular is the preferred option for developing a new project, particularly if it requires advanced backend features. It is advisable to engage someone who is knowledgeable in Angular rather than having to learn both TypeScript and Model-View-Controller (MVC).
