With many JavaScript frameworks available for client-side and server-side rendering, choosing the perfect framework for designing the latest web application can take time and effort. This blog aims to create some simple functionality using ReactJS vs AngularJS to give you a better understanding of what it would take to get an application off the ground.
In this blog, we will explain the comparison between AngularJS and ReactJS. ReactJS is a JavaScript library for building user interfaces, whereas AngularJS is a typescript-based open-source front-end application platform. By reading, you will know which framework helps develop a web application.



Let’s hold a look at some points about ReactJS vs AngularJS.

DOM MANIPULATION:

ReactJS:

ReactJS is all about components. ReactJS performs one-way data binding, which modifies the view. It creates the virtual DOM, so it does not update the Real DOM directly as it updates the virtual DOM.

AngularJS:

AngularJS uses two-way data binding, which directly updates the model view controller and the DOM.


LIBRARY COMPATIBILITY

ReactJS:

ReactJS uses a JavaScript library developed by Facebook that specializes in providing data as HTML and is extensively used by websites such as Imgur, Airbnb, and Netflix.

AngularJS:

AngularJS uses JavaScript language to run the application programme. It uses typescript that requires type definitions for every library.

DATA BINDING:

React JS:

ReactJS uses a one-way data binding approach, so the data flows only in a uni-direction, making the work easier. It makes it easy for the developers to debug the process with extensive applications.

AngularJS:

It uses a two-way data binding approach and connects the DOM to Model data using the Controller. With its two-way binding, performance can be degraded as every binding has a watcher to spot the changes in DOM.

COMPONENTIZATION

ReactJS:

Components in React are just JS functions. ReactJS offers an excellent and easy way to build component trees. With the help of functional programming language, it makes component definitions declarative.

AngularJS

Angular’s component hierarchy is sophisticated, i.e. Structure and functionality behave as an integral whole. AngularJS is based on the MVC model. This JavaScript framework provides a reliable solution for AngularJS development projects. In AngularJS, the object is initialized by the Controller and then transformed into HTML to create the view for the user. We can easily break code into several files by using many services provided by AngularJS, such as controllers, factories, and directives.


EVENT HANDLERS

ReactJS

In ReactJS, event handlers set custom attributes on the HTML elements you create for ReactJS development. ReactJS uses its own internal state to handle any event that cannot be modified through external programs.

AngularJS

Directives are used to make AngularJS great. In AngularJS, event handlers are typically assigned to many portions of your view via directives. AngularJS uses an ng-click demand that can be placed on an HTML element, which hooks up a click handler that previously existed on the local scope.


PERFORMANCE

ReactJS

React uses many techniques to reduce the number of expensive DOM operations required to update the UI. It uses the concept of virtual DOM. When an HTML document is loaded, it creates a lightweight DOM tree from JavaScript objects. So, whenever the user inputs any data in the browser, React creates a virtual DOM and matches it with the previously saved DOM. It sends only unmatched data on the server and optimizes its performance while avoiding replicating data.

AngularJS

AngularJS creates a watcher for each binding for changing any value in the DOM. It relates the new deal with the initial value and runs the $digest loop after the view updates. This loop checks all the saved values tracked by the watchers. With too many watchers, the app performance can decrease in the Angular JavaScript framework.

CONCLUSION:


We know that ReactJS and AngularJS are different from each other, but they both accomplish the same thing. Both are the best frameworks for developing any web application. If we talk about performance, ReactJS is good because of the concept of virtual DOM, whereas AngularJS performs low. If we talk about coding purposes, AngularJS is good as developers need to write less code here.

ReactJS is search engine optimization friendly and compatible with heavy traffic. On the other hand, AngularJS offers stable development and testing along with reliability. Thus, programmers choose which framework to decide to develop any web application.
