May 25, 2023

Category Angular, React

Ranging from startups to small, medium, and large businesses to enterprises worldwide, everyone is implementing robust applications utilizing enriched frameworks. One such popular framework is JavaScript and there are many popular JavaScript frameworks that are offered for frontend development.

Two such leading names in the world of JavaScript frameworks that are often compared are Angularjs vs Reactjs.

When it comes to known frontend development frameworks, be it React or Angular, developers have been appreciating the goodness of both these technologies big time. It is even more difficult for organizations to choose between the two. Angular Vs React is an interesting evaluation that depends upon several parameters.

This article takes you through an overview of both technologies, their features, pros and cons, organizations using them, and then the difference between Angular and React through a parameter-based comparison matrix. It also emphasizes situations indicating when to use which – React or Angular.

What is Angularjs?

AngularJS is a well-known open-source JavaScript-based application framework, especially meant for dynamic web app development. It leverages HTML as the template language and changes static HTML into dynamic HTML. It generates an environment that is easy to understand, fast to develop, and communicative.

Powered by Google and built on TypeScript, it has been a leading, fully featured, client-side framework to create high-performing web and mobile apps. As a structural framework for building dynamic web apps, it offers enterprise-ready web app development solutions with component-based architecture and dynamic, single-page web apps too.

There is a wide collection of integrated libraries and features such as routing, two-way data binding, dependency injection, and client-server communication that speeds up web development. There are effective developer tools that are best fit to develop small to enterprise-grade applications.

What is Reactjs?

ReactJS is a powerful open-source front-end JavaScript library that offers development companies excellent features to develop exclusive interfaces and experiences for high-performance solutions. Its scalability, adaptability, and flexibility help developer streamline the process of front-end development to offer reliable React development services.

React showcases a component-based architecture and declarative views that helps developers build fast, complicated, and interactive user interfaces, seamlessly. Powered by Facebook, it goes by the ‘learn once, write anywhere’ fundamental and makes the code easy to understand and operate.

React empowers developers to create user interfaces from reusable UI components. It uses server-side rendering for a flexible, performance-driven solution. It promotes a component-dependent architecture with modular and self-contained components, faster development, easy maintenance, and reusability of the logical part.

Angularjs vs Reactjs: Difference Between Angular and React

Parameters Angular React
Overview An open-source framework for the creation of dynamic web apps, a part of the MEAN stack, compatible with code editors An open-source library for the creation of user interface components, used to develop reusable HTML elements for front-end development
Developed By Google Facebook (Meta)
Year of Release 2009 2013
Written in TypeScript JavaScript
Type of Technology MVC structured framework JavaScript library
Performance High-performance framework as it uses real DOM and two-way data binding High-performance library as it uses virtual DOM and runs on single directional data flow
Data Binding Two-way data binding (bidirectional) – Guarantees that the model state automatically changes when any change is made One-way data binding (unidirectional) – UI elements cannot be altered without updating the corresponding model state
Learning Curve It has a steep learning curve, with a complex component management system It has a moderate learning curve, empowers faster application development
Best Suitable For Interactive, dynamic, and highly active enterprise web applications, complex enterprise apps, progressive web apps and single-page apps Large apps with continuous differing data, UI components, modern web apps, natively rendered hybrid apps, social networking apps, eCommerce apps
User Interface Components Material Design components to ease out user interface creation Material-UI library & dependencies to offer UI components
