Features of AngularJS
- Data-binding: AngularJS follows the two-way data binding. It is the automatic synchronization of data between model and view components.
- Model View Controller(MVC) Framework: MVC is a software design pattern used for developing web applications. The working model of AngularJS is based on MVC patterns. The MVC Architecture in AngularJS is easy, versatile, and dynamic. MVC makes it easier to build a separate client-side application.
- Services: AngularJS has several built-in services such as $http to make an XMLHttpRequest.
- User interface with HTML: In AngularJS, User interfaces are built on HTML. It is a declarative language which has shorter tags and easy to comprehend. It provides an organized, smooth, and structured interface.
- Dependency Injection: AngularJS has a built-in dependency injection subsystem that helps the developer to create, understand, and test the applications easily.
- Active community on Google: AngularJS provides excellent community support. It is Because Google maintains AngularJS. So, if you have any maintenance issues, there are many forums available where you can get your queries solved.
- Routing: Routing is the transition from one view to another view. Routing is the key aspect of single page applications where everything comes in a single page. Here, developers do not want to redirect the users to a new page every time they click the menu. The developers want the content load on the same page with the URL changing.
Jordan Walke, who was a software engineer at Facebook, develops it. Initially, it was developed and maintained by Facebook and was later used in its products like WhatsApp & Instagram. Facebook developed ReactJS in 2011 for the newsfeed section, but it was released to the public in May 2013.
Features of ReactJS
- Components: ReactJS is all about components. ReactJS application is made up of multiple components, and each component has its logic and controls. These components can be reusable, which help you to maintain the code when working on larger scale projects.
- One-way Data Binding: ReactJS follows unidirectional data flow or one-way data binding. The one-way data binding gives you better control throughout the application. If the data flow is in another direction, then it requires additional features. It is because components are supposed to be immutable, and the data within them cannot be changed.
- Virtual DOM: A virtual DOM object is a representation of the real DOM object. Whenever any modifications happen in the web application, the entire UI is re-rendered in virtual DOM representation. Then, it checks the difference between the previous DOM representation and new DOM. Once it has done, the real DOM will update only the things that are changed. It makes the application faster, and there is no wastage of memory.
- Simplicity: ReactJS uses the JSX file, which makes the application simple and to code as well as understand. Also, ReactJS is a component-based approach which makes the code reusable as your need. It makes it simple to use and learn.
- Performance: ReactJS is known to be a great performer. The reason behind this is that it manages a virtual DOM. The DOM exists entirely in memory. Due to this, when we create a component, we did not write directly to the DOM. Instead, we are writing virtual Components that will turn into the DOM, leading to smoother and faster performance.
AngularJS Vs. ReactJS
||Angular 1.7.8 on 11 March 2019.

||Open Source MVC Framework
||Open Source JS Framework
||Unit and Integration Testing
||It manages dependencies automatically.
||It requires additional tools to manage dependencies.
||It requires a template or controller to its router configuration, which has to be managed manually.
||It doesn't handle routing but has a lot of modules for routing, eg., react-router.
||Fast, due to virtual DOM.
||It is best for single page applications that update a single view at a time.
||It is best for single page applications that update multiple views at a time.
