However, deciding which is the best amongst React vs Angular is still a question. Let’s see what are the prime comparison factors of both frameworks and how to pick the suitable one for your business app.

 

What is Angular?

 

Angular

 

Angular is a JavaScript (JS) framework for developing web applications. It is developed and maintained by Google, and is designed to make it easier to build dynamic, responsive user interfaces. Angular uses a declarative approach, which makes it easier to reason about the structure of an application and to manage its state.

It also offers a powerful set of tools used for building reusable components & services, as well as for debugging & testing. Angular is often used in combination with other technologies such as TypeScript, RxJS, and Firebase to build powerful, full-featured web applications.

Angular framework, also known as Angular 2+ is a complete rewrite of AngularJS (also known as Angular 1), and was first released in September 2016. AngularJS was first released in 2010 by Google and quickly gained popularity as a powerful framework for building web applications. However, as web development evolved and new challenges emerged, the Angular team at Google decided that a complete rewrite was necessary to address these issues.

This framework introduced a number of new features and improvements over AngularJS, including a more powerful template language, improved performance, and support for mobile devices. Angular also adopted a more component-based architecture, which made it easier to build and maintain large-scale applications.

What is React?

react

 

React is a JS library for building UIs. It was created by Facebook (FB) and is now maintained by a developer community. React allows developers to build reusable components that can be easily combined to create complex user interfaces.

One of the key features of React is its ability to efficiently update the user interface in response to changes in the underlying data. This is achieved through a process called “virtual DOM diffing,” which compares the current version of the user interface with a new version, and only updates the parts of the interface that have actually changed.

React also encourages a component-based approach to building user interfaces. React components are self-contained units that represent a piece of the user interface, such as a button or a form. These components can be easily reused across different parts of the application, and can even be shared across different projects.

React is widely used in web development and is supported by a large and active community. Many popular libraries and frameworks, such as React Native and Gatsby, are built on top of React and leverage its strengths. React is also supported by a large ecosystem of developer tools, including debugging and testing tools.

Performance

Angular and React are both popular JavaScript libraries for building web applications, but they have some key differences in terms of performance.

Angular is a full-featured framework that provides a lot of built-in functionality and can be more complex to set up and use. However, it can be more efficient for large, complex projects with a lot of data and heavy user interactions. This is because Angular uses a two-way data binding system, which can improve performance by reducing the amount of code needed to update the view and manage the application’s state.

React, on the other hand, is a more lightweight library that focuses on building user interfaces. It uses a virtual DOM, which can improve performance by minimizing the number of changes that need to be made to the actual DOM. This can make React particularly well-suited for smaller projects and projects with simpler data structures. However, for complex projects, React can require more code and be less performant than Angular.

In summary, Angular is better suited for large and complex projects, while React is better for smaller projects and simple data structures.

Popularity Growth

Both Angular and React are popular JavaScript libraries for building web applications and have seen significant growth in popularity over the years. However, React has seen more consistent and steady growth in popularity, while Angular’s popularity has fluctuated somewhat.

React was first released by Facebook in 2013 and has since become one of the most widely used JavaScript libraries for building user interfaces. According to the State of JavaScript survey, React has consistently been one of the most popular JavaScript libraries since its release, with over 70% of developers reporting that they have used it.

 

Angular vs react: Popularity

 

Angular, on the other hand, was first released by Google in 2010 and has had a slightly more uneven popularity trajectory. According to the same survey, Angular’s popularity has fluctuated somewhat over the years, with its usage dropping after the release of Angular 2 but then rebounding with the release of Angular 4 and 5. However, Angular still has a significant number of users, with around 60% of developers reporting that they have used it.

It’s worth noting that this data is based on a survey, so it’s not a definitive measure of popularity but gives a good idea of the relative popularity of the frameworks.

 

Two-way data binding & One-way data binding

Angular and React handle data binding differently. Angular uses two-way data binding, while React uses single-way data binding.

In a bidirectional data binding process, any changes made to the view (the user interface) are immediately reflected in the model (the data) and vice versa. This means that when a user makes a change to the view, the model is automatically updated, and when the model is updated, the view is automatically updated as well. Angular uses two-way data binding by default, which can help simplify the process of keeping the view and model in sync.

In contrast, React uses unidirectional data flow, which means that changes made to the model are automatically reflected in the view, but changes made to the view are not automatically reflected in the model. Instead, React uses a virtual DOM which helps to minimize the number of changes that need to be made to the actual DOM, improving performance.

One-way data binding allows for more explicit control over the flow of data and can be more efficient for larger and more complex projects. Two-way data binding is more suited for smaller projects with simple data structures and can help simplify the process of keeping the view and model in sync.

It’s worth noting that React does not completely lack two-way data binding, it can be achieved by using a library such as MobX or Redux.

Code Quality

Both Angular and React can be used to produce high-quality code, but they have some differences in terms of the structure and organisation of the code.

Angular uses a component-based architecture, which means that the code is organised into different components that represent different parts of the user interface. Each component has its own template, logic, and style. This structure can help ensure that the code is well-organised and easy to understand, but it can also make the code more complex and difficult to read if not written and organised properly.

React, on the other hand, uses a functional component-based architecture, which means that the code is organised into small, reusable functions that return elements to be rendered. This approach can make the code more concise and easier to read, but it can also make it more difficult to understand the overall structure of the application if not written and organised properly.

Both frameworks encourage the use of best practices such as writing modular and reusable code, adhering to a consistent coding style, and properly documenting the code.

Testing

Both Angular and React have built-in testing capabilities, but they are implemented differently.

In Angular, testing is built-in and integrated into the framework using Jasmine as the testing framework and Karma as the test runner. Angular also has a powerful dependency injection system that makes it easy to mock dependencies for testing.

React, on the other hand, does not have built-in testing capabilities. Instead, it relies on third-party libraries such as Jest and Enzyme for testing. Jest is a testing framework that provides a way to run and structure tests, while Enzyme is a library that allows you to manipulate and traverse React components for testing.

Both Angular and React have good testing support, but React relies more on third-party libraries, while Angular has more built-in features.

Ultimately, the choice of whether to use Angular or React for testing will depend on your specific use case and what you feel most comfortable with.

Learning Curve

The learning curve for Angular and React can vary depending on a developer’s experience and background.

Angular is a full-featured framework that provides a lot of built-in functionality for building web applications. It has a large and complex syntax and requires a good understanding of concepts such as dependency injection, directives, and services. This can make it challenging for developers new to Angular to understand and get started with the framework.

React is often considered to have a gentler learning curve than Angular, as it does not have as many features and concepts to learn as Angular does. However, for a more complete development experience, React requires the use of additional libraries and tools to build a complete web application.

In general, Angular has a steeper learning curve than React, but it also provides more built-in functionality and has a more complete development experience. React has a gentler learning curve, but it requires the use of additional libraries and tools to build a complete web application.

Server-side Rendering optimizations

Both Angular and React support server-side rendering (SSR) to some degree, but the implementation is different for each framework.

Angular has a built-in mechanism for server-side rendering called Angular Universal. It uses a technology called TransferState to transfer the application state from the server to the client, which allows the client to continue where the server left off.

React, on the other hand, does not have a built-in mechanism for server-side rendering. Instead, developers must use third-party libraries, such as Next.js, to implement SSR in a React application. These libraries use a technique called “static generation” to pre-render the application on the server and send the generated HTML to the client.

In summary, Angular has built-in support for server-side rendering, while React requires the use of third-party libraries for this functionality.

UI Components Maintainability

Both Angular and React are popular JavaScript frameworks for building web applications, and they both have their own strengths and weaknesses when it comes to code maintainability.

Angular is a fully-featured framework that provides a set of tools and conventions for structuring and maintaining code. It uses a component-based architecture, which can make it easier to understand and manage the relationships between different parts of the codebase. Additionally, Angular’s use of TypeScript, a typed superset of JavaScript, can help to catch errors and improve code readability. It also uses material design components for easy maintenance of code.

React, on the other hand, is a more lightweight library that focuses on building reusable UI components. It uses a virtual DOM to efficiently update the display, which can make it easier to optimise the performance of the application. However, because React is more flexible than Angular, it may require more effort to ensure that the codebase is well-structured and easy to maintain.

Ultimately, the maintainability of code in either Angular or React will depend on the specific development practices and best practices followed by the team using them.
