What’s the Difference Between Angular and React JS?

Angular and React JS are both widely used for creating dynamic mobile applications. However, it is important to note that Angular is a framework, whereas React JS is a library, and so comparing the two directly is not meaningful. That said, both are capable of achieving the same result, albeit through different approaches.

Angular is a framework, whereas React is a library. React focuses solely on the user interface, whereas Angular follows the Model-View-Controller (MVC) concept, providing access to all three layers simultaneously.

Intro to Angular

Google’s Angular is still one of the most popular Javascript frameworks available, and is often referred to as a framework rather than a library. It is specifically designed to render webpages in a web browser.

The Typescript support offered by the framework offers a level of security akin to what programmers working in C# and Java are used to. Microsoft’s TypeScript is an extension of the JavaScript programming language.

In accordance with the Apache License, the code may be available on GitHub. It is a common practice to assign a type to a variable, function argument, or output in Typescript.

Brief Introduction to React JS

Facebook’s React JS is a widely-used JavaScript library, with a committed community of developers and users. It provides an efficient way to display the various elements of a website’s user interface (web framework). Hierarchies of components can be represented in a straightforward way, and the components’ structure can be presented using HTML tags.

As a consequence, it is largely responsible for the visual representation and user input. Single-page web applications typically begin with the React JS package, although it may also be pre-rendered on the server with the assistance of Node.js.

Use-casesExtensive infrastructure for creating softwareUsed mostly in the creation of user interface elements
The State of the Art in Code QualityUses just HTML files and a unified syntaxThere are two syntaxes in use here; JSX is used to bundle together HTML and Javascript.
TestingAlthough Jasmine is widely used, some developers have complained that it is too complicated to understand.Jest, Facebook’s popular testing framework, is favored due to its ease of use.
MaintainabilityCohesive and uniform coding structureCode that is both flexible and easily modified
Help From NeighborsGoogle, joining the likes of HBO, McDonald’s, Apple, Adobe, Forbes and Nike, has publicly declared its support for the platform, despite its smaller user base.More people use it, and major corporations like PayPal, Twitter, Facebook, Netflix, Uber, Microsoft, and Yahoo all use it as well.
SizeDifferent packages vary in size, however on average you can expect to pay around 500KB. We highly recommend single-page web or app development.This lightweight library (116 KB) is highly recommended if future development of the application you’re building is planned.
DifficultyLengthy learning curve that requires familiarity with TypeScript and Model View Controller.There’s no need for any prior expertise, and the lesson is both interesting and fun.
Replacements and TransfersThe recommended frequency of updates is twice a year, or every six months.End users may profit from migrations more and have less downtime with the help of custom scripts.
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

Comparing Angular vs React in Terms of Their Relative Popularity

A survey conducted by Stack Overflow in 2023 revealed that React was the most popular framework, with 40.14% usage and 25.12% interest. Angular was fourth in terms of popularity (22.96%) and demand (8%).

To gain an insight into the frequency of searches for a specific tool over a period of time and the popularity of various app development environments, Google Trends can be consulted. The average monthly searches for Angular on this index are 68, whereas for React, the figure is 84.

True downloads matter just as much as total queries. According to the most recent data from NPM, React is seven times more popular than Angular.

Based on these three metrics, it’s clear that React is the preferred framework over Angular.

Jasmine is a popular choice amongst Angular developers for creating tests and assertions. Although many engineers enjoy working with it, there have been some complaints about the complexity and lack of readability of its output.


Angular offers a well-defined framework which makes it easy to modify and re-use code. React, meanwhile, has a flexible architecture that is also user-friendly.

Angular’s structure is more complex, yet stable, whereas React’s design is simple yet adaptable, as it utilises new libraries when layers of code are generated dynamically.

Community in Angular

Due to its increased usage, the React community is significantly larger. It has been adopted by a number of leading organisations, such as PayPal, Twitter, Facebook, Netflix, Uber, Microsoft, and Yahoo.

The size of the user base is another benefit of platforms that offer frequent updates, such as React. While there is not a large amount of literature documenting the most recent advancements, the support provided by niche forums helps to fill the gap.

As a result of developers’ early mistrust and Angular’s perceived complexity, the framework’s user base has shrunk significantly.

The credibility of the framework is further reinforced by Google’s endorsement and the fact that many large corporations, including HBO, McDonald’s, Apple, Adobe, Forbes, Nike and Microsoft, utilise it.


In comparison, the React library has a size of 116KB, whereas the size of an Angular package typically ranges from 500KB. It is recommended to use React for applications which may be extended in the future.

It appears that React has several advantages over Angular, however, is there any justification for continuing to deploy Angular? It should be noted that Angular is the best option for creating lightweight single-page web applications.

The Challenge of Angular vs. React

Upon gaining an understanding of the key components of a given framework, you will have reached a conclusion. Acquiring proficiency with Angular necessitates familiarity with TypeScript and Model-View-Controller, both of which will increase the amount of time taken to complete the process.

React does not require any prior knowledge and is free from complex structures and traditional conventions. The accompanying tutorial makes learning React an enjoyable experience.

Improvements and Switching

When the update is released, it will be necessary to make some modifications to your code. Therefore, it is essential for developers to check for any uploaded changes to ensure a successful upgrade.

React’s individualised migration scripts allow clients to make changes with ease. It is recommended that Angular be upgraded every six months in order to ensure any improvements are maintained.

Differences Between Angular and React in Terms of Their Parts

Angular’s integrated toolkit incorporates a broad range of UI elements, such as layouts, pop-ups, buttons, indicators and more, which enables the inverse technique to be used when constructing components and frameworks. This approach makes it straightforward and efficient to introduce user-specific modifications to the interface.

The React Community is responsible for the creation and distribution of all React tools (free and commercial) on the React website. To utilise these tools, a separate library must be installed and then a complex interface must be configured through React.

Development Time

How quickly anything is made relies on the developer’s access to libraries. And in this aspect, every instrument has its own advantages.

React has a more measurable architecture, whereas Angular offers a faster and easier process for creating web applications. Ultimately, the best option for your project will depend on your priorities.


Both frameworks facilitate the development of both single- and multi-page applications. In both instances, mobile programming is achievable through the incorporation of complementary technologies such as React Native and NativeScript.

While both frameworks may be used to create mobile apps, they rely heavily on those created by others (Cordova for React and Ionic for Angular).

Conclusions: Should You Use Angular or React?

When comparing head-to-head, neither React nor Angular show an advantage over the other. Both are popular frameworks, each offering their own advantages and drawbacks, as can be seen in this comparison.

Angular is a versatile technology that can be utilized for both web and mobile app development, whereas React is primarily designed for UI development and requires additional libraries to unlock its full potential.

When considering whether React could replace Angular, it ultimately depends on the type of project being undertaken. React’s focus on front-end development, as well as its compatibility with other applications, makes it an ideal choice for projects that require a high number of interactive User Interface (UI) components or ones that rely heavily on them.

Angular is the recommended choice for developing a new project, especially if it requires advanced backend features. It would be preferable to select someone experienced in Angular as opposed to needing to learn TypeScript or Model-View-Controller (MVC).
