Front-end developers know how important it is to decide on the best technology framework between Angular and React for their projects. Both frameworks have been serving the front-end development world for a pretty long time now. Both have their own charms, popularity, and pros and cons among front-end developers.

While Angular.js was the initial framework launched by Google over a decade back, Angular appeared only in 2016 and with a total makeover. It continues to be maintained by Google. While the former relied mostly on JavaScript, the latter relies on TypeScript.

React, on the other hand, has been in existence since 2010. As opposed to the Angular framework, it is a comprehensive library that was introduced by Facebook and continues to be supported by the social media giant. The technology has constantly evolved since its inception and has gained massive popularity in the past few years. It essentially relies on JavaScript and JSX.

But if you want to choose one that will prove to be perfect for your project requirements, this post will help you see a reasonable comparison of both JavaScript frameworks.

There are several factors to draw the line between Angular vs React. Let us go through a few of these and find out which is the best fit for your project.

Let’s get started.

Angular vs React: A Detailed Comparison

1. Performance

While both Angular and React frameworks are great for building large-scale apps, there’s a striking difference in terms of the performance they render. This is because of the different types of DOMs (Document Object Models) they use.

This brings us to the question: What are DOMs?

DOMs are programming APIs that define the logical structure of HTML and XML documents and allow to change the contents, layout, and even structure of a document.

Angular- This is a full front-end framework that operates on real DOM (Document Object Model) which allows to update the entire tree structure of HTML tables until reaching the required data. Real DOM deals with numerous data requests, as a result of which it often slows down the apps, thereby affecting the performance.

React- It uses virtual DOM which allows to access and change document contents, layout, and structure, without rewriting the entire HTML document virtually. This results in faster updates and better performance, no matter what size app it is. Updating a specific user profile detail like, the email address is possible without updating the entire HTML structure.

Key Takeaway

Due to the real DOM that Angular operates on, the framework deals with loads of data requests and ends up being a burden for your projects. The end result? Heavier application and slower performance.

React, on the other hand, allows you to create large web applications that can change data without updating the entire HTML structure, which makes it a wonderful choice for building scalable and fast applications.

2. Data Binding

When it comes to the data binding structure, the two JavaScript frameworks vary vastly. The data binding structure impacts the stability of the code.

While choosing one of the two for your front-end development project, consider the kind of flexibility you’re looking at for your debugging processes.

Angular- It uses both one and two-way data binding which allows automatic data store and UI updates. This results in true data encapsulation, meaning that there is reduced need to do complex changes to DOM. However, it is important to remember that it is a good framework choice for objects that are relatively simple. For heavy data manipulation, React often proves to be a better choice.

React- It uses the one-way binding, which means more stable codes and easier to debug apps. React apps are organized as a series of nested components that are functional. This framework often proves to be a better performer than Angular because of its one-way data binding structure.

Key Takeaway

For simpler data manipulation requirements, Angular could be a great choice since it’s a lot simpler to work with. Later, you can always turn to React once your project grows.

3. Component Architecture

Angular- It is based on reactive programming, meaning that components can respond to external events well. This JavaScript framework relies on two different kinds of components viz. Container components (or “smart” components) and Presentation components (or “dumb” components). The former know how to get data, while the latter have to be fed with data.

React- This framework allows you to create components and structure them into complex and dynamic User Interfaces (UIs). You can seamlessly integrate this framework into any project even if it’s written in Angular. But, if your project is React-based, it will need multiple integrations like, Babel, Redux, and Webpack, to use it to its full capacity.

Key Takeaway

Angular and React both have strong ecosystems. Your choice must depend on how data flows in your application.

4. Technology Architecture

While both frameworks serve the same purpose of front-end web development, their technology architecture differs significantly.

Angular- This framework allows developers to decide the structure of their applications and start coding directly rather than choosing libraries or components. While this is a big advantage as it removes a lot of hassle, it often makes the framework less flexible.

React- This is not a framework but a large library. To use it as a framework, developers usually integrate it with a variety of tools and libraries such as React Cosmos, StoryBook, Bit, Evergreen, and Reactide, among others. However, it requires a lot of decision-making, maintenance, and handling updates and migrations.

Key Takeaway

React requires developers to make their own design choices and keep up with the latest updates. If you want apps that are easy to maintain and migrate, Angular would be the best choice.

Main Points to Remember

Want to build a simple and small-sized application?

React is a better choice.

Are scalability and diverse features important to you?

There is nothing like Angular.

Is your team highly skilled in JavaScript?

React is your best option.

Do you want to choose a framework that is easier for your developers to get started in and integrate with third party libraries?

Well, React it is.

Do you have a cross functional team doing lots of development, especially for large projects?

Give Angular a try.

Conclusion

Both frameworks enjoy equal popularity in the technology world.

Some of the world’s biggest projects built using ReactJs include Facebook, Netflix, Instagram, Whatsapp, and Airbnb. Some popular projects built using AngularJs include Google, Nike, Telegram, PayPal, and Upwork.

While going through the comparison between Angular and React in this post, you might have noticed that they both have their pros and cons.

So, what is your ideal fit between Angular vs React?

Well, you can work with either one and still end up making a failed product. There really is no better choice among the two technologies.

It’s all a matter of preference.

Therefore, it’s important to choose one that your development team can dedicatedly utilize to its full potential.

In the end, the choice must depend on your purpose, project requirements, and development process.
