To recap, Angular is a powerful Javascript framework, while React is just a library. But both are crucial for building complex user interfaces for the front end. So, do we really need a comparison between Angular vs React? Hell Yes! There have been a lot of similarities and unique features in each of these JavaScript technologies, giving a state of confusion to web developers in terms of effectiveness. However, to sort out things for you, we have broken down this Angular vs React comparison into chapters to help you grasp the topic and make an informed decision on which turns out to be the best front-end solution for your project.  Let’s get started!

Chapter 1: All About Angular

Before moving on to the main topic “Angular vs React” it would be a great idea to understand each of these JavaScript resources deeply. So, here’s what you should know about Angular. 

What Is Angular?

Angular is a platform and framework for building web and mobile applications using TypeScript and HTML. TypeScript is a language that extends JavaScript with features like static typing and classes.  Angular is an open-source project created by Google engineers and other contributors. The framework allows you to create single-page applications that are fast, responsive, and easy to maintain. One of the features that makes Angular stand out from other frameworks is its two-way data binding. This means that any changes in the user interface are automatically reflected in the data model, and vice versa.  If you are familiar with AngularJS, you might think that Angular is just a newer version of it. However, that is not the case. Angular and AngularJS are different frameworks with different architectures and concepts. AngularJS uses JavaScript as its core language, while Angular uses TypeScript. Angular is more modern, modular, and performant than AngularJS.

#2 Usefulness

Angular and React are both useful tools for front-end developers, as they have different strengths and features. They can help developers create both small and large apps with more flexibility and functionality.  Here are some of the ways they are used in different scenarios.  Angular  Angular is a popular choice for building cross-platform apps, as it can help businesses save costs and resources. However, Angular is also a very sophisticated platform, and it requires a lot of skill and effort to master it. Therefore, only experienced developers will usually opt for Angular for their projects. The framework also has some advantages that make web apps faster and more efficient.  Angular uses AOT, which stands for Ahead-of-Time compilation. This means that it converts Typescript and HTML code into JavaScript before the browser loads the code. This results in a quicker rendering of the web app.  React  React is quite straightforward. You can learn it and start a project in a much shorter time than other platforms. Because you will be using plain JavaScript, you will have access to the vast amount of JavaScript knowledge available on the web.  Moreover, React allows you to use JSX, which is a syntax that combines HTML and JavaScript in your code. This makes it easier for developers to write and read code. As we know, React has server-side rendering. This means that it is SEO-friendly, as it can handle most search engines without any problems.

#3 Features

React and Angular are both popular frameworks for building web applications. They have some common features, but also some differences. Let’s compare some of the main features of Angular and React with a detailed explanation.  Angular  Angular is a full-fledged framework that offers many features for web development. Here are some of them: 

  • Based on TypeScript: Angular is built using TypeScript, which is an extension of JavaScript. TypeScript helps developers to find and fix errors in large applications and debug them easily. 
  • Supports Ajax and HTTP: Angular has built-in support for Ajax and HTTP, which enables users to connect and interact with backend services in Angular and improve performance. 
  • Uses components: Angular started with the Model View Controller (MVC) architecture, but later switched to using components. Components are reusable pieces of UI that can communicate with each other. 
  • Angular CLI: The Angular Command Line Interface (CLI) is one of the most praised features of Angular by developers. It automates the whole development process by creating and configuring the application. 

React  Now let’s see some of the top features of React: 

  • Declarative UI: React uses HTML to create the UI of the application. HTML is lighter and simpler than Java. 
  • Flexibility: React offers a simple UI design and provides many extensions to support the application architecture. 
  • Clean Abstraction: React does not force the user to learn its complex internal functions. Internal processes like Digest cycles are not required for the users to understand. 
  • Virtual DOM: React provides a virtual DOM that copies the existing DOM and stores it in the cache memory, saving the user from re-rendering the DOM trees every time the HTML code is updated.

#4 Learning Curve

When we want to learn a new framework or library for web development, we might wonder how hard or easy it is to master it. This depends on many factors, such as the features, size, and design of the technology. In this section of Angular vs React comparison, we will compare the learning curve of these JavaScript resources.  Angular  Angular is a full-fledged framework that offers a lot of functionality and flexibility. However, this also means that it has a steeper learning curve than some other technologies. One of the reasons is that Angular requires you to learn TypeScript, which is a superset of JavaScript that adds some extra syntax and features.  TypeScript is specific to Angular and not widely used in other frameworks or libraries. Another reason is that Angular has some concepts and techniques that are different from other technologies, such as dependency injection.  Dependency injection is a way of managing dependencies between components, but Angular implements it in a unique way that might be confusing for developers who are used to other approaches.  React  Meanwhile, React is a lightweight and simple library that focuses on building user interfaces. It does not require you to learn a new language, as long as you have a good grasp of JavaScript. React also has some built-in features that make it easier to learn, such as dependency injection, which is native to React and does not need any special configuration or syntax.  However, React also has some challenges and quirks that you need to understand and master, such as state management and components. State management is the way of keeping track of the data and changes in your application, and components are the reusable pieces of UI that you can create and combine.  React has its own way of handling these aspects, and you might need to adapt to new technologies and tools to work with them effectively.

#5 Dependency Injection (DI)

Dependency injection is a design pattern where a class receives its dependencies from an external source instead of creating them itself. For example, a class called “Computer” may need a class called “Processor”. The “Processor” class is the dependency in this case.  Angular  Angular supports dependency injection, which makes it easier to test and debug the code. Another benefit of dependency injection is that a class can be reused with different dependencies. For example, you can use different kinds of “Processors” in “Computer” to create different computers. This way, you don’t have to change any code in the Computer class.  React  React has a built-in feature for dependency injection in JSX. DI in React happens through props and children.

#6 Essential Tools

No ma what you use between Angular and React, both require some essential tools for coding, setting up, rendering, and testing your projects.  Here are some common tools that Angular and React developers use: Angular  Some of the tools that Angular developers use are
