In the ever-evolving world of web development, developers have an abundance of choices when it comes to selecting the right technology stack for their projects.

Among the numerous options available, two front-runners stand out: React and Angular.

These JavaScript frameworks (or in the case of React, a library) are widely used for building user interfaces, and both have their own strengths and weaknesses.

In this article, we'll explore five compelling reasons to use React JS instead of Angular.

Quick Takeaways

  • React is a JavaScript library primarily focused on building user interfaces, while Angular is a comprehensive JavaScript framework that offers a complete solution for building web applications.
  • React is often favored for its flexibility and minimalism, unlike Angular, which is a full-fledged framework.
  • React's virtual DOM and efficient reconciliation algorithm make it faster than Angular when rendering UI components. This speed advantage is particularly noticeable in large and complex applications.

What is Angular?

 Angular and React

Angular: A Comprehensive JavaScript Framework

Angular is a robust and comprehensive JavaScript framework that was initially developed by Google.

It has evolved significantly since its inception and is designed to facilitate the development of dynamic, single-page web applications (SPAs).

SPAs are web applications that load a single HTML page and dynamically update the content as the user interacts with the application, without requiring full-page reloads.

Versions of Angular: AngularJS and Angular

Angular has gone through significant transformations over the years, resulting in two main versions:

  1. AngularJS (Angular 1.x): The first version of Angular, often referred to as "AngularJS," was released by Google in 2010. AngularJS introduced a novel approach to web development by introducing features like two-way data binding, dependency injection, and a declarative approach to building user interfaces. While AngularJS was revolutionary in its time, it had limitations in terms of performance and scalability.
  2. Angular (Angular 2+): To address the shortcomings of AngularJS, the Angular team at Google completely rewrote the framework, resulting in "Angular," often simply referred to as Angular 2 and later versions. Angular introduced a wide range of improvements, including a more modular architecture, better performance, improved tooling, and enhanced scalability. Angular's modern design principles and powerful features have made it a popular choice for building large-scale, enterprise-level applications.

What is React?

On the other side of the spectrum, React is a JavaScript library created by Facebook.

React is primarily focused on building user interfaces, and it has gained immense popularity for its simplicity and flexibility.

It is known for its component-driven architecture, which allows developers to create reusable UI components efficiently.

Here are the latest statistics on the benefits of React JS instead of Angular:

  • Popularity: According to the 2023 Stack Overflow Developer Survey, React is the most popular JavaScript framework, with 40.14% of respondents using it. Angular is in fifth place, with 22.96% of respondents using it.
  • Performance: React is generally faster than Angular. This is because React uses a virtual DOM, which only updates the parts of the DOM that need to be updated, rather than the entire DOM.
  • Learnability: React is generally easier to learn than Angular. This is because React has a simpler syntax and a smaller API.
  • Community: React has a larger and more active community than Angular. This means that there are more resources available for React developers, such as tutorials, documentation, and libraries.
  • Job market: There are more job openings for React developers than for Angular developers. This is because React is more popular and in demand.

In conclusion, the latest statistics show that React has a number of advantages over Angular, including:

5 Reasons why developers consider React to be better than Angular

 React Technology
  1. Flexibility and Control: React is often favored for its flexibility and minimalism. Unlike Angular, which is a full-fledged framework, React is a JavaScript library that focuses primarily on the view layer of an application. This means that React gives developers more control over their project's architecture and allows them to choose additional tools and libraries per their project requirements. Developers appreciate this flexibility because it lets them tailor the development stack to suit their specific needs.
  2. Component-Based Architecture: React's component-based architecture is a fundamental reason why developers choose it over Angular. In React, user interfaces are broken down into reusable components, which makes code more modular and maintainable. Developers can create and manage UI elements as standalone components, reducing code duplication and making it easier to test and debug. This component-driven approach enhances code reusability, which is crucial for large-scale and complex projects.
  3. Performance and Virtual DOM: React's performance benefits are often cited as a significant advantage. React employs a virtual DOM (Document Object Model) that acts as a lightweight representation of the actual DOM. When changes occur in a React application, React first updates the virtual DOM and then calculates the most efficient way to update the real DOM. This process minimizes direct manipulation of the real DOM, resulting in faster rendering and a smoother user experience, especially in applications with frequent updates.
  4. Large and Active Community: React has a vast and active community of developers and open-source contributors. This ecosystem provides developers with access to a wealth of resources, libraries, and tools. The extensive community support means that developers can easily find solutions to common problems, stay updated with the latest trends, and benefit from a wide range of third-party libraries and components. This active community is a significant advantage for developers when it comes to learning and growing their React skills.
  5. React Native for Cross-Platform Development: Another compelling reason to choose React is its extension, React Native. React Native allows developers to build mobile applications for both iOS and Android platforms using the same codebase. This streamlines the development process, reduces the need for platform-specific development, and allows developers to leverage their existing React skills to create native mobile apps. This cross-platform capability is highly attractive for companies looking to target a broader audience without doubling their development efforts.

In summary, React's flexibility, component-based architecture, performance optimizations like the virtual DOM, a large and active community, and the ability to use React Native for mobile development make it a compelling choice for many developers.

However, it's important to note that the choice between React and Angular ultimately depends on the specific project requirements and developer preferences.

Each technology has its strengths and weaknesses, and the decision should be based on the unique needs of the project at hand.

Key Features of Angular
