Do you know that part of a movie in which the protagonist faces a difficult choice? This is exactly how front-end developers feel when faced with the decision to choose Angular vs React for their project.

Both frames have their strengths and their own followers. And according to Statista’s survey of the Most popular technology skills in the JavaScript technology stack worldwide in 2022 React is the most popular and demanded skill, while Angular ranks fourth.

Although popularity can be a decisive factor, it is important to go deeper and analyse which framework best suits your project.

In this article, we will break down the key differences between React and Angular so you can make an informed decision for your next front-end project. So grab your notepad and get ready to take notes. Let’s start.

6 factors to consider when choosing a front-end frame

A list of pros and cons may not be enough to determine which framework is the right choice. So, before diving into the differences between React and Angular, let’s take a step back and consider the factors when choosing a front-end framework.

Here are some factors to keep in mind before making a decision:

1. Project needs

It goes without saying that each application project has its own requirements. If you have seen that one project uses Angular and another React, it does not mean that you should follow its example automatically. Instead, assess your needs and see which framework best aligns with them.

On the other hand, if you need to create a business-level application with robust features and scalability, Angular could be your framework.

2. Performance

Great performance has to do with compatibility, speed and size. Since React and Angular are widely used, it is important to note their performance in terms of load time, rendering speed, and overall size of the framework. After all, no one wants to have to deal with an application that loads slowly.

3. Learning curve

Learning something new is never easy, but it shouldn’t be too difficult either. A steep learning curve can be a major barrier for developers, especially when working with tight deadlines. Therefore, it is important to evaluate the learning curve of each framework:

Are there many tools and resources available to help developers?

Are there active communities and support forums to solve problems?

4. Community support

Beginners, and even experienced developers, often turn to community support to solve problems, learn new techniques, and stay up-to-date on the latest features.

GitHub It is a good place to measure the activity and support of the community. You can also consult forums on Reddit, blogs and social network groups dedicated to each framework.

5. Opportunity to expand

All projects start with a small team and limited resources, but that does not mean that they will continue like this. As your application grows and demands increase, you will have to expand it without major obstacles.

From this perspective, consider the growth potential of web applications in each framework. Will it be easy to add new features and modules as the application grows? Will you need more resources and time to grow?

6. Maturity and trends

Trends come and go, but maturity remains. When it comes to Angular vs React, you’ll find that both frameworks have been around for quite some time. This makes it both mature and reliable in terms of stability and support.

However, it is also important to be aware of the latest trends. You don’t want to invest time and resources in a framework that may become obsolete in a few years.

Now that we have seen the factors to consider we are going to immerse ourselves in the key differences between React and Angular.

What is React?

React, a JavaScript library used by Facebook, was opened in 2013. This framework introduced the concept of component-based architecture into the mainstream of web application  development. React consists of creating user interfaces with JavaScript.

Component-based architecture enables developers to create a seamless user experience and complex user interfaces in the blink of an eye. ¿And guess what? These components are reusable, which speeds development. In addition, it is perfect for mobile development, since it allows you to reuse sections of the application just by changing the view.

React follows the principle of “learn once and write anywhere”, making it the best option for creating fast and scalable applications. Large companies like Netflix, Airbnb and Walmart love React.

Main features of React

React has the following features that make it a popular choice among developers:

JavaScript syntax extension (JSX): React uses JSX, a JavaScript syntax extension that combines HTML and JavaScript. JSX code is transformed into JavaScript using transpilers like Babel, allowing for faster execution and facilitating the development of high-performance applications.

Virtual DOM: Instead of updating the entire DOM, React uses the virtual DOM to improve application performance. This means that only the necessary changes are synchronised with the actual DOM, which translates into faster charging times. By reducing unnecessary rendering, React improves the overall user experience.

Unidirectional linkage of data: React supports one-way data linking, in which data flows from parent components to children. This approach gives developers more control over the application and simplifies troubleshooting and debugging.

Reusable user interface components: React’s reusable code components simplify the process of creating and managing user interface code for large applications. These components, with their own logic and control, allow you to create interactive IUs efficiently.

Use third party libraries: React is highly adaptable, making it easy for developers to integrate third-party libraries. This allows for greater customization and flexibility in terms of features and functionalities.

Advantages of React

As a Javascript library, React offers several advantages for front-end development. Some of them are:

Minor encoding

React, with its component reuse, offers the advantage of requiring less coding. By reducing the amount of code needed, React allows developers to focus more on the logic and functionality of their applications, resulting in increased productivity and efficiency. This simplified coding approach enables developers to create robust and scalable applications more easily.

High performance

React is known for its high performance capabilities, thanks to its efficient rendering and the implementation of virtual DOM. By using virtual DOM, React can quickly render web components, resulting in minimal load times. This not only improves the user experience, but also the general positioning of your applications in search engines.

Supports the development of web and mobile applications

React is not limited to creating amazing web interfaces. It goes further with React Native, which allows you to easily create hybrid mobile applications for Android and iOS. No more thinking that React is only for web development. Facebook has taken it to the next level with a powerful framework for the development of native mobile applications.

Easy debugging process

Experience the comfort of the practical debugging tools React offers. These tools are accessible as browser extensions for Chrome and Mozilla, making debugging easier. With improved bug reports and an optimised one-way data stream, React is distinguished as the framework that makes debugging easy.

A strong community

Supported by an incredible community, React has a wide network of users who actively contribute to its web application development company . This means that whenever you encounter an obstacle while working with the library, you will easily find useful solutions.

What is Angular?

Angular is a web framework developed and maintained by Google. It burst onto the scene in 2010 under the name AngularJS and quickly gained popularity thanks to its powerful features, such as two-way data linking and dependency injection. Backed by a tech giant, Angular became one of the most popular web frameworks of its time.

This open source JavaScript framework is undoubtedly a favourite among front-end developers to create efficient and dynamic web applications. Along with React, Angular offers a robust solution for presenting and manipulating data effectively.

When it comes to large-scale business applications, Angular is an excellent choice. Companies like Microsoft, AT&T and Google use Angular for their web development needs.

Main features of Angular

These are some of the key features that make Angular stand out:

Bidirectional data linking: Angular supports one-way and two-way data linking, giving developers the flexibility to choose between the two based on their project’s specific requirements.

Dependency injection (DI): An Angular design pattern that efficiently manages dependencies, improving flexibility and modularity of the application. Separate the different parts of the application, making it easy to test and debug isolated components.

CLI angle: Angular CLI is a powerful command line interface that allows developers to easily create, manage and preview Angular applications. With LiveReload support, it provides a seamless development process.

Advantages of Angular

While React is known for its simplicity and user interface, Angular offers a more complete solution with powerful functions.

The advantages of working with Angular functions are listed below:

MVC architecture

Angular follows an MVC (Model-Viewer-Controller) architecture, in which the controller acts as a mediator between the Vista and the Model. This structure facilitates complex application management and allows developers to work on specific components without affecting other parts of the application.

Automatic synchronisation

The Bidirectional Data Link Angular feature facilitates perfect data synchronisation between the Model and the View. Consequently, these components are automatically updated each time the data is modified or adjusted. This process occurs in real time, saving engineers from the need for changes and saving them additional time and effort manually.

Get end-to-end and unit tests

With Angular, you have the power to perform unit tests and end-to-end tests for your application. ¿And the best? It doesn’t matter how many developers or users you have: you can try any part of your application! The Angular framework even includes tests as a standard feature. It is very easy to start and test all the components at once. Thanks to Angular’s dependency injection, you can inject simulated data into the controller for testing.

Using TypeScript data types

When you use Angular, you can easily obtain data from the TypeScript code on your website and respond to user input without the need to write additional code. This means that you can integrate third party libraries without the need for additional code. Additionally, Angular promotes clean code development by leveraging TypeScript syntax. Compared to conventional JavaScript, TypeScript allows you to write less code and easier to maintain, making it perfect for creating large-scale applications.

Compatible with major browsers

Angular offers compatibility with major browsers, making it a cross-platform power. Whether you use Chrome, Firefox or any other browser, an Angular application runs smoothly on Windows, MacOS and Linux operating systems.
