Angular Vs React: Which is Better for Frontend Development?

When it comes to front-end development, choosing the right framework can significantly impact your project’s success. Several options are available, but Angular and React stand out as two of the most popular frontend frameworks.

In this blog, we will look into a comprehensive comparison of Angular and React. It provides you with the insights needed to decide which framework aligns best with your project requirements.

Whether you want to revamp your front end or begin with your new project, this blog will provide you with the necessary knowledge to make an informed choice.

So let’s dive into the comparison and determine which framework is ideal for front-end development.

What is Angular?

Angular is a popular open-source framework developed and maintained by Google. It is designed to build dynamic and feature-rich web applications. Angular is a complete redesign of AngularJS, which was first released in 2010. It follows the MVC architectural pattern.

Angular provides a comprehensive set of frontend development features and tools, including data binding, dependency injection, and routing.

What is React?

React is a widely-used open-source JavaScript library developed by Facebook. It is primarily used for building user interfaces. React utilizes a component-based approach that allows developers to create reusable UI components that efficiently update and render when data changes.

Differences Between Angular and React

The major differences depend on several parameters. So let’s discuss them individually in detail.

Popularity

Both Angular and React are highly popular and widely adopted front-end frameworks in the development community.

Popularity

Angular gained popularity in 2010 when it was first introduced, especially for developing single-page applications. It has continued evolving with its new releases and features and remains a preferred choice for web application development.

However, as per a survey, React secured the second position in the list of most used web frameworks by developers worldwide. It also gives the advantage of rendering and a simple way of reusing the UI components.

Performance

These frontend frameworks have distinct abilities to build high-performing web apps.

As Angular has a bidirectional data binding process, each binding requires a watcher to look after all the modifications done in DOM. It checks all the values that are changed, along with older values that are tracked via watchers. Therefore, it might impact Angular’s performance negatively.

On the contrary, React offers high performance due to the Virtual DOM tree, which is built on the server. When a user interacts with the website, such as filling out a form, React builds a new virtual DOM and compares it with the earlier saved DOM. This complete process is done on the server, reducing the browser’s load.

Need Assistance in Choosing the Right Framework?

Let our experts guide you through the Angular vs. React debate. We’re here
to provide personalized advice tailored to your project’s needs.

Data-Binding

Angular utilizes a two-way data binding that binds Document Object Model(DOM) values to model data. This shows that the view and model get updated whenever the user interacts with an input field and initiates a value to the app.

On the other hand, React supports one-way data binding. It offers unidirectional behavior for your application. Hence, you can easily know where data is changed, as when the UI components get changed, the model state remains the same without any changes. This also helps to reduce complexity. Also, debugging self-contained components of large React apps is simpler than large Angular apps.

Dependency Injection

Angular consists of an inherent dependency injection subsystem that enables developers to build, understand and test the applications effectively. Dependency injection supports making components reusable, maintainable, and testable.

React doesn’t provide any option for a built-in container for dependency injection. However, you don’t have to find any way to inject dependencies instantly into your React project. You can take the help of some tools to inject dependencies instantly in a React app.

Directives and HTML Templates

Angular comprises its directives to work on DOM. The two most standard directives present in Angular include ng-bind and ng-app. Also you can build your own directives as well. In short, you can use specific and standard directives to bind DOM elements into Angular apps.

Angular utilizes plain HTML templates, which is a great thing. Moreover, these templates are passed to the compiler via DOM elements and not as strings. This one thing helps in a better workflow. Also, this helps in the quick manipulation, extension, and reusability of templates.

Unlike Angular, React doesn’t provide any division into templates and directives or template logic. Here, template logic should be written in a template only.

DOM

The Document Object Model (DOM) graph represents a user’s current browser view. Both frameworks rely on DOM.

Angular uses a real DOM, where the entire tree structure is updated when a change is performed. It solves the drawback by utilizing change detection to change required components only.

React uses a virtual DOM. Any change even a single element can make without updating the entire structure.

Language

Angular uses TypeScript as its primary language. TypeScript is a superset of JavaScript that enhances developer productivity by adding static typing and additional features.

React uses JavaScript, specifically ES6+ syntax, where components are typically written in JavaScript. It allows developers to leverage the latest features of the JavaScript language. However, it can also be used with TypeScript if desired, but not supported natively.

UI Components

Angular offers different material design components, such as layouts, buttons, and pop-ups. It enables smooth & quick configuration of UI. While in React, you must first install Material-UI Library and Dependencies developed by the community. These UI tools offer many UI components giving you free and paid options.

Testing

In Angular, testing can be easily done due to its built-in testing functionality. Also, one can perform testing using tools such as Karma and Jasmine. Components testing can be done with ease due to incorporating dependency injection into the structure.

React widely uses Redux, which reduces the task of storing and managing component states in big complex applications with a lot of dynamic elements.

It gives a chance for developers to add an application state in a single object and allow all the other components of the app to access the application state without affecting child components. Hence, it quickly tests applications and logs data changes using hot reloading and other tools.
