ReactJS vs AngularJS

Difference between ReactJS and AngularJS

AngularJS

AngularJS is the JavaScript framework that is open source, and it is also used to build a dynamic web application. It is developed in 2009 by Misko Hovery and Adam Abrons, now Google maintained it. The latest version of AngularJS is 1.7.8 on March 11, 2019. It uses the properties of HTML and JavaScript and mainly used for creating single-page applications. It includes with HTML page by using a <script> tag. It binds the data to HTML with expressions and also extends the HTML simply by adding built-in-attributes with the directive.

Features of AngularJS

There are several features of the AngularJS that are as follows:

  1. Data-binding: AngularJS allows for two-way data binding. It is the automatic synchronization of data between the model and the view components.
  2. POJO Model: POJO stands for the ‘Plain Old JavaScript Model,' which is used by AngularJS. It provides objects that are spontaneous and well-planned. It makes AngularJS easy to use and self-sufficient.
  3. MVC (Model View Controller) framework: MVC is nothing but a software design pattern that is used for developing web applications. The AngularJS working model is mainly based on MVC patterns. The architecture of MVC in AngularJS is dynamic, comfortable, and versatile.
  4. Services: AngularJS includes several built-in services like $http for making an XMLHttpRequest.
  5. User interface with HTML: In AngularJS, HTML is responsible for creating user interfaces.  AngularJS is a declarative language that includes shorter tags that are easy to comprehend. It gives a smooth, organized, and structured interface.
  6. Dependency Injection: AngularJS has an existing dependency injection subsystem that makes the developer task easy for creating, understanding, and testing the applications.
  7. Active Community on Google: As we know, Google maintains the AngularJS, so in case of any maintenance issue, many forums are available where the queries get solved.
  8. Routing: Routing is the mechanism of transition from one view to another view. It is the key aspect for single-page applications where everything is on one page. Developers don't wish every time to redirect the users to the new page after every menu click. The developer requires the loading of content on the same page with the changing of URL.

ReactJS

It is the essential front-end library that is developed by a software engineer name Jordan Walke in facebook. Facebook was the first that has developed and maintained it, and after that, used in its products like Whatsapp and Instagram. Facebook was the first who established the React in 2011, but it was presented to the public in May 2013.

ReactJS is also an open-source JavaScript library that is used for creating the user interface for a single-page application. According to MVC, React is the ‘V,' which stands for View. There are several components to build the ReactJS app; these components act as the heart of all of the React applications. When these components are added to other elements, then together, they will allow creating complex applications.

Features of ReactJS

  1. JSX: JSX is an acronym of JavaScript XML. It is an extension of the JavaScript syntax. Its syntax is similar to XML or HTML. This syntax is processed into JavaScript Calls of React Framework. It enhances the ES6 so that the texts like HTML can co-exist with JavaScript react code. It is not mandatory to use JSX, but it is advisable to use it in ReactJS.
  • One-Way Data Binding: ReactJS is designed in a manner that follows the unidirectional data flow or one-way Data Binding. One-way data binding is advantageous as it provides better control throughout the application. When the data flow in another direction, then the additional features are required in it. It happens because the components are thought to be immutable, and the data within them cannot be modified. The pattern Flux helps to keep data unidirectional. It provides more flexibility to the application, which leads to increase efficiency.
  • Virtual DOM: Virtual DOM is nothing but a representation of actual DOM. It works like one-way data binding. At every modification in the web application, the complete UI is re-rendered in virtual DOM representation. Then, it analyses the difference between the new DOM (which is re-rendered) and the representation of previous DOM. Once it gets completed, real DOM modifies the things that are changed. It saves memory and makes the application faster.
  • Simplicity: As we know, ReactJS uses JSX, which provides simplicity to the application and makes the code understandable. ReactJS follows a component-based approach, which provides the reusability to the code. It makes it easy to learn and use.
  • Components: ReactJS is made up of components, in which each component has its logic and controls. The components are reusable that helps in maintaining the code when working on large scale projects.
  • Performance: ReactJS has excellent performance. Because of this feature, ReactJS becomes much better to compare to other frameworks. Behind this reason, there is a concept of managing virtual DOM. The DOM is nothing but a cross-platform and programming API that deals with HTML, XML, and XHTML. The DOM entirely exists in memory. Because of this, whenever we create a component, we did not write them directly to the DOM; instead of this, we write virtual components that turn into the DOM leads to smoother and faster performance.
