It is a component-based framework built on typescript, which is used to develop scalable web applications. Angular js offers a huge collection of well-integrated features and libraries.

It follows an MVC architecture, supports client-server communication, routing, cross-platform development ability. It offers developers various tools to build scalable projects.

They can build single-page applications to an enterprise-grade application. The angular team at Google & developer communities around the world offer dedicated support.

What is React?

React is an open-source JavaScript library developed by Facebook. It is a credible frontend development tool based on JavaScript and JSX (an extension of PHP).

The React Library divides the webpage into many single components and eases the task of interface development. Facebook developed React JS in 2012 to help them manage the Facebook ads with simple HTML coding. In 2013 Facebook made React Js open source.

Since then, it is being used by millions of developers and technology enthusiasts. The Facebook development team and various developer communities maintain, and support React.

Fundamental differences between Angular and React

Though Angular & React are Frontend development choices, there are fundamental & characteristics differences. Let’s understand these differences between Angular and React in the table below:-

Fundamental Difference  Angular JS React JS
Structure It is a structural framework to build dynamic web applications It is a JavaScript library that allows developers to create UI components
Model It is based on Model View Controller (MVC) model It is based on Virtual DOM
Written in It is based on Typescript It is based on JavaScript
JavaScript Library Integration  It doesn’t offer the ability to add a JavaScript library to the app source code It enables developers to add a JavaScript library to the app source code
Debugging and Testing It offers to debug and testing for entire project using a single tool It needs a set of different tools to perform testing and debugging on project
Use of Library Angular is a complete solution in itself React can be packaged with other programming libraries
Installation Time It is easy to set up but takes more time to deliver the project It takes more time to set up, but project delivery is blazingly fast
Learning Curve It requires a lot of training efforts, especially for beginners It is easier to learn, though it is difficult to learn when augmented with Redux
Flexibility It offers a limited amount of flexibility and freedom It gives more freedom to select architecture, libraries, and tools to develop applications
Data Binding It uses a two-way binding method, which ensures the automatic change in the model when any change is made It uses one-way data binding, which doesn’t allow a change in UI components without updating the corresponding model state
Community Support A massive community of technology enthusiasts and developers. Supported by Facebook developer communities
Documentation The documentation is slower due to the ongoing development process The documentation is relatively faster if we compare it with Angular

Key Features – React Vs. Angular 

In this section, we will discuss and have a brief overview of few important features of Angular and React.

1. Universality

React – It is a framework utilized for mobile and web development. To develop mobile apps, it can be incorporated with Cordova. We can also use React Native framework to build mobile apps. React can be used to develop both multi-page and single-page applications.

React Native framework

Angular – Angular is also preferred for both mobile and web development. For mobile apps development, we can use Ionic. Angular also uses an additional mobile development framework – Native Script. Angular can be used to develop both multiple-page and single-page web apps.

2. Self-Sufficiency

React – React is a framework for User Interface development. React application requires additional libraries, such as Redux, Helmet, or React Router.

They are used for state management and optimization, interaction with API, and routing. Functions like project generation, data binding, form validation, dependency injection, or component-based require additional libraries or modules to be installed.

Angular – It is a full-fledged framework for app development, which doesn’t need modules or libraries. Angular package includes all such features like project generation, form validation, data binding, component-based routing, and dependency injection.

3. Performance

React – Here the performance has been enhanced with the introduction of the virtual DOM. Since all virtual DOM trees are built of the server and are lightweight, the load on the browser reduces to a great extent.

It uses a unidirectional data-binding process, which is unidirectional, and these bindings are not assigned, watchers. This helps in the reduction of workload on the applications in a real-time environment.

Angular – As far Angular performance is not so great in the case of dynamic and complex web applications. The major cause behind that is Angular’s bidirectional data binding, where each binding is assigned a watcher to keep a track of all changes.

This loop continues until all the watchers along with associated values are checked. This process creates performance bottlenecks as more watchers are created to support data bindings in complex applications.

Google has made great improvements in its recent Angular updates, to enhance its capabilities up to a certain extent. But still, it is not preferred for complex applications which use a higher degree of data binding.

4. App Structure

React – The fundamental structure of React offers developers wider freedom to choose. It is mandatory to design the application structure at the beginning of project, it’s quite cumbersome sometimes.

Apart from that, React JS offers only the View layer, whereas the Model and Controller layers are added using additional libraries. React application architecture is component-based. Where the code is composed of React components and rendered by React DOM library. 

App Structure

Angular – On the other hand, Angular’s structure is complex and fixed, which is more suitable and preferred by experienced developers. It is of three layers – Model, View, and Controller. In this structure, the object responsible for the Model is initiated by the Controller, and the View layer helps it to display.

The Angular application code consists of different components, each being coded in four separate files. An HTML file defines the view, a TypeScript implements the component, a CSS file defines the stylistic features, and a special file is dedicated for testing purposes.

The structural logic of the application can be displayed by linking these files by writing them in the application directive. All Angular components are reusable, which gives it an upper hand over React.

5. UI Components

React – User Interface tools for React are designed by the community. React portal also offers a plethora of open-source, free, and paid UI/UX components. All you need is to install the additional library, Material UI library, and Dependencies to use UI material design components in React.

Angular – It offers an in-built UI material toolset, to use a variety of pre-built UI/UX design components. Angular UI components toolset has various components like buttons, indicators, layouts, form controls, and pop-ups. This makes UI configuration a lot faster and easier for developers.

6. Dependency Injection

React – It does not completely support dependency injection. As it does not follow the idea of data immutability and functional programming. Instead, it offers a global state for all the objects and components.

Angular – It completely supports dependency injection, which makes it way better than React on this front. Angular enables different lifecycles for different stores. It’s a preferred framework when dependency injection is a must.

7. Data Binding

React – Data binding is a synchronization process between the View and Model layer. React is usually augmented with Redux, which helps developers to work with immutable data and ensures unidirectional data flow. It also uses predictable Unidirectional binding, which assists with the debugging process.

Angular – It works with mutable data and bidirectional data binding. The benefits of immutable and mutable data are a matter of debate. But it is always preferred to work with bidirectional data. The fact is bidirectional data binding impacts the performance. Angular automatically develops a separate watcher for each binding in real-time.

8. Tools Support

React – It is supported by multiple code editors such as Sublime Text, Atom, or Visual Studio. In order to bootstrap an application project, one can simply use Create React App (CLI) tool. For server-side rendering requirements, we can use the Next.js framework.

Multiple tools could be used for testing and quality assurance, such as Enzyme (component testing), Jest (JS code testing), React-unit (for unit testing), and so on. React offers React Dev Tools to perform app debugging in the development mode.

Angular – It also supports a variety of code editing tools, such as Sublime Text, Aptana, and Visual Studio. We can set up a project with Angular CLI and Angular Universal tool for Server-side rendering. Angular can be fully tested with a single tool.

We can use Protractor, Karma, and Jasmine to perform end-to-end testing. It offers browser extension augury to perform application debugging.

9. Learning Curve

React – Once can easily learn React js if he/she has adequate knowledge of JavaScript. It is minimalistic, with no dependency injection, no complicated features, and no classic templates. Thus, it is extremely easy to learn and use.

Angular – Learning concepts of associated components is a bit difficult due to the large library. Angular is difficult to learn, as component management is intricate. It uses a lot of unnecessary syntaxes.

Angular comes with many complicated features as part of the core framework. Thus, its mandatory for developers to learn it. It’s difficult to learn if we compare it with React.

10. Language

React – It is based on JavaScript ES6+ along with JSX script. JSX is indeed an extension for syntax, which makes JavaScript code like an HTML written code. Thus, understanding and writing the code is easier.

The typographic errors and other lapses can be identified easily. React is augmented with Babel (code transition tool) to compile the JSX code in a browser.

Angular – It can use TypeScript or JavaScript, which is considered a superset of JavaScript. It is utilized for scalable project development.

TypeScript is compact than JavaScript, which enables developers to navigate easily, spot the errors in lesser time. Angular uses a Code refactoring process, which makes the code faster and simpler.
