But when it comes to deciding which one is best suited for your business, the choice can be daunting. In this blog post, we’ve discussed the key differences between both, helping you make an informed decision that aligns with your business objectives.

In this tech landscape, Angular and React have emerged as two popular front end frameworks, each with its own set of strengths and capabilities. These frameworks have redefined how developers craft modern, dynamic, and user-friendly web applications. However, for business owners and decision-makers, selecting the most suitable framework can feel like navigating through a maze of technical jargon and complexities.

Before choosing, you need to know exactly what Angular is? And how does it work? How about React – what sets it apart? So, let us break it down into simple terms and give you a broad idea through the Angular vs. React comparison. By understanding the basics of each framework, you’ll be better equipped to make an informed decision for your business.

Angular vs React: Brief Overview

Angular and React are two of the most popular JavaScript frameworks used for building modern web applications. While both are powerful tools, they have distinct differences in terms of their architecture, approach, and ecosystem. Let’s take a brief overview of each:

What is Angular?

Google launched Angular.js in 2009. It is an open-source, client-side web framework that helps Angular developers resolve issues related to single-page web development that were viewed multiple times. It is used for building dynamic, single-page web applications (SPAs) and large-scale enterprise applications.

Benefits of Angular

• Developers find it easier to develop a customized Document Model Object (DOM)
• Offers support of Angular libraries, which helps in creating template solutions
• Has in-built injection subsystem dependency
• Enables the development of single pages separately and combines them with the components to see the outcome
• Offers single routing and an eye-catching user interface with data binding
• Provides an extension to HTML syntax and helps build reusable components through directives
• Synchronize the data between the model view and component

Drawbacks of Angular

While Angular is a powerful framework for building web applications, it’s important to consider its drawbacks:

• Angular has a relatively steep learning curve compared to other frameworks 
• The framework requires writing a significant amount of boilerplate code to set up components, modules, services, and routing 
• Its extensive features and built-in functionalities can sometimes result in a performance overhead, especially in larger applications 
• Angular follows an opinionated architecture that requires developers to adhere to certain conventions and patterns
• It has a larger bundle size compared to some other frameworks that impact loading time 
• It adds complexities for developers when they are managing dependencies and ensuring compatibility

What is React?

Conversely, React is a different technology and many times developers prefer using React over Angular. But what makes developers choose React over Angular?

To be precise, React is an open-source dynamic JavaScript library developed by Facebook in 2013. It helps create amazing user interfaces and build single-page applications and mobile apps. It is based on the concept of components, which are reusable, self-contained building blocks that represent a part of the UI. These components encapsulate both the structure and behavior of a portion of the user interface, making it easier to manage and update complex UIs.

Benefits of React

• Supports code reusing 
• Has a component-based architecture that facilitates easy component import 
• Follows a simple debugging process
• Has an intuitive user interface
• Supports React native library that offers high and efficient performance
• Ensure faster updates with both the front-end and server-side support
• JavaScript extension syntax offers HTML quoting to render sub-components
• Allows developers to develop universal or isomorphic web applications with server-side rendering
• Supports both iOS and Android platforms without any hassle
• Follows view-oriented approach

Drawbacks of React

• Complicated JavaScript extension syntax is hard to learn for novice web developers
• Has a complex and stiff learning process
• It is not a framework but a library
• Frequently releases new tools and documents, making it difficult for developers to understand codes 
• Require configurations while incorporating ReactJS into MVC
• Initiates frequent changes in architectures

A Detailed Comparison: React vs Angular

The prime differences between React and Angular depend on a few aspects. Let’s discuss them individually!

UI Component

The UI component is one differentiating factor in the battle of Angular vs. React. Angular supports an integrated material tech stack, equipped with numerous pre-designed components adhering to material design principles. The built-in feature streamlines UI configuration, enabling swift and effortless setup.

On the other hand, in React, the community actively develops various UI tools, offering free and paid options accessible through the React portal.

Languages

Angular is developed using TypeScript, a superset of JavaScript that offers better tooling support and adds optional static typing and other features. Hence, you need to hire AngularJS developers with specific technical expertise and knowledge of TypeScript.

Contrary to this, React uses JavaScript (ES6+) for writing applications, but React operates at the view layer. You can use any language that complies with JavaScript, including TypeScript or CoffeeScript. Hence, React.js development is the hands down winner of React vs. Angular comparison as it is more flexible when it comes to language support.

Componentization

Angular features a highly complicated and fixed structure as it depends on 3 layers: Controller, View, and Model. Using Angular, developers can break down the app code into several files. It enables the repeated use of templates or elements in several parts of the app.

Meanwhile, React does not select the same architecture. It provides an easy option to build element trees. The library features functional programming in which declarative component definitions are found. React codes are structured logically and can be read easily. Developers don’t need to write codes.

Data Binding

Data binding is another deciding factor in the Angular vs React.js comparison. Angular primarily uses a two-way binding approach, where changes to the model in the view are automatically reflected in the model and vice versa. It means if the data changes in the view, it automatically updates the model and vice versa.

Along with it, Angular uses Zone.js and change detection to identify changes in the application state and update the view accordingly. It may lead to performance overhead, especially in complex applications. Moreover, Angular uses HTML templates with special Angular syntax, like interpolation, property binding, event binding, etc., to bind data and handle events in the view.

React follows one-way data binding, meaning data flows in a data direction: from parent components to child components. When data changes, React re-renders the component tree efficiently. React uses a virtual DOM to efficiently update the actual DOM.

When data changes, React compares the virtual DOM with the actual DOM and makes required changes, reducing the number of DOM manipulations. Furthermore, React uses JSX, a syntax extension that allows you to write HTML-like code within JavaScript, making it easy to define the structure of your UI components and bind data to them.

Document Object Model (DOM)

Angular allows direct manipulation of the DOM through its templating system and APIs like ElementRef and Renderer. It allows developers to interact with the DOM directly and access native DOM elements or apply low-level DOM manipulations.

To optimize performance, Angular employs various change detection strategies, including default change detection and OnPush change detection. However, excessive DOM manipulations can impact performance negatively.

Conversely, React uses a virtual DOM, which is a lightweight copy of the actual DOM. When data changes, React updates the virtual DOM first, then compares it with the real DOM to identify the minimal set of changes needed, and finally updates the actual DOM accordingly.

React discourages direct manipulation of the DOM. Instead, it encourages developers to work with React’s virtual DOM and use a declarative approach to define UI components. Direct DOM manipulation is generally avoided in React, as it can lead to inconsistencies between the virtual DOM and the actual DOM, potentially causing performance issues and bugs. 

Toolset

Angular utilizes various code editors like Visual Studio, Aptana, and Sublime Text. Along with it, Angular CLI helps build the project, and Angular Universal supports server-side rendering. Developers can use AngularJS tools to execute operations and fully test Angular using a single tool like Jasmine, Protractor, or Karma which makes it more beneficial than React.

Like Angular, React uses many code editing tools, including Visual Studio, Atom, and Sublime Text. It utilizes the Create React App tool to bootstrap a project and the Next.js framework for server-side rendering. To test an application written in React, developers can use many tools for various components.

Server Side Rendering

Angular provides built-in support for server-side rendering through its Angular Universal module. Angular Universal enables the rendering of Angular applications on the server side using Node.js, allowing you to generate fully rendered HTML pages before sending them to the client.

Server-side rendering with Angular Universal can improve SEO by ensuring that search engine crawlers receive fully rendered HTML content, making it easier to index and rank pages. It also improves performance by reducing time-to-content for users, particularly for initial page loads.

Opposite to it, React itself does not provide built-in support for server-side rendering. However, there are several third-party solutions available, like Next.js and Gatsby.js, which enable server-side rendering with React. Next.js is a popular React framework that supports server-side rendering out of the box.

It simplifies the process of building SSR React applications by providing features like automatic code splitting, prefetching, and routing. Server-side rendering with React can improve perceived performance by delivering pre-rendered HTML to the client, allowing content to be displayed more quickly, especially on initial page load.

Bundle Size 

Angular facilitates Ahead-of-Time (AOT) compilation, which compiles templates and components during the build process, resulting in smaller bundle sizes compared to Just-in-Time (JIT) compilation. It has features like lazy loading of modules, allowing developers to load parts of the application on-demand, reducing the initial bundle size. Moreover, the framework employs optimization techniques like dead code elimination and minification to further reduce bundle size.

Unlikely, React allows developers to optimize bundle size by selectively importing required components and libraries, reducing unnecessary dependencies. It offers tools like React.lazy and Suspense for code splitting, enabling the loading of components asynchronously, thus minimizing initial bundle size. It provides tree-shaking capabilities, removing unused code during the build process to further reduce bundle size.

Code Quality and Maintainability 

Angular supports TypeScript, which enhances code quality by detecting errors during development and enabling better IDE support and code navigation. Provides a powerful CLI (Command Line Interface) tool that automates services and modules, streamlining code maintenance processes.

It offers a robust architecture with well-defined design patterns like MVC (Model-View-Controller) and services, facilitating code scalability and maintainability in larger applications.

React employs JSX (JavaScript XML) syntax, which allows developers to write HTML directly within JavaScript, facilitating clear and concise code writing. It provides a lightweight and flexible framework, enabling developers to choose their preferred libraries and tools for state management, routing, and other functionalities.

Testing

The testing and debugging of the Angular IO is possible for the entire project using one tool like Karma, Protractor, and Jasmine. Moreover, Angular provides testing utilities, including TestBed, ComponentFixture, and integration testing of Angular components, services, and directives.

React commonly utilizes Jest as the testing framework, along with libraries like React Testing Library and Enzyme for unit and integration testing of components. Jest’s snapshot testing and mocking features streamline testing workflows. Thus, it would be easy to test applications if you hire ReactJS developers with strong technical skills.

App Functionality

Angular is a full-featured framework that provides built-in solutions for various aspects of web development, including components, services, routing, forms, HTTP client, and state management (with Angular services and RxJS).

Angular has an opinionated structure and prescribes best practices for organizing code and building applications. It can be beneficial for large teams or projects where consistency and maintainability are crucial. Though the functionality will also depend on the AngularJS development company you have chosen to handle the project.

Unlikely, React follows a component-based architecture, allowing developers to break down complex UIs into smaller, reusable components. The approach promotes modularity and makes it easier to manage and scale applications.

Moreover, React is more flexible in terms of technology choices. It’s often used in conjunction with other libraries and tools for state management, like Redux and MobX. For routing, it uses React Router and Formik to handle forms. React grants the freedom to developers to pick and choose the best for their specific needs.

Thus, if you are building a large-scale application with complex requirements and prefer a framework that provides comprehensive solutions, Angular’s opinionated structure and built-in features might be advantageous.

If you prioritize flexibility and want the ability to tailor your technology stack to specific project needs, React’s component-based architecture and ecosystem of third-party libraries offer more flexibility and customization options. However, you must partner with a reliable ReactJS development company to manage the development operations and streamline the process.

Popularity

Angular vs. React popularity is a vast topic to discuss in a few words. Both React and Angular have garnered significant attention and adoption within the developer community. According to the Stack Overflow Developer survey conducted in 2023, React ranked in the 1st position, and Angular acquired 4th position.  

Additionally, React gained 203,000 stars on GitHub, while Angular has approximately 86,700 stars. These statistics indicate that React holds a slightly higher level of popularity compared to Angular, as evidenced by its larger GitHub star count and higher ranking in the survey. In 2023, there were approximately 2 billion websites, among which almost 13,441,975 used React to develop user interfaces.

In 2016, Angular 2.0 was launched, representing a complete overhaul of AngularJS with numerous enhancements and novel features. Subsequently, Angular has undergone continual refinement and advancement through subsequent releases, maintaining its status as a favored option for web application development. Later, its popularity faced challenges due to competition from other JavaScript frameworks and libraries, such as Vue.js and React.

When it comes to Angular vs. React popularity, React is the indisputable winner as it has been consistently maintaining higher popularity than Angular. Its superiority lies in rendering optimizations, virtual DOM implementation, and seamless version migration capabilities. Moreover, React excels in facilitating UI component reusability and streamlining task completion.

These and other features establish React as the premier JavaScript front-end framework and developers prefer to use React for app development. It is a plus point for React in the React.js vs. Angular battle.

Learning Curve

Compared to React, Angular has an immersive learning curve. The Google Angular IO framework provides several options to fix a specific issue. It has a complicated component handling system that is familiar with various concepts and languages, such as pipes, templates, RxJS, dependency injection, Typescript, etc.

Moreover, this framework is growing steadily, allowing developers to check the latest trends in the Angular ecosystem and enhance their skills accordingly.

On the other hand, the same does not go for the ReactJS framework. React enables developers to learn and build an app in the React ecosystem if they are familiar with JavaScript. Despite the frequent updates, it offers several helpful resources for beginners to learn the framework and plan for creating an app. For this reason, developers usually select React, giving it an upper hand in Angular.js vs. React.js comparison.
