Which Javascript Framework Is Better Between Reactjs Vs Angularjs?





With so many JavaScript frameworks available for client-side and server-side rendering, choosing the perfect framework for designing the latest web application can be a difficult task. The purpose of this blog is to go over creating some simple functionality using ReactJS vs AngularJS to give you a better understanding as to what it would take to get an application off the ground.
ReactJS is a JavaScript library that is used for building user interface whereas AngularJS is typescript based open source front-end application platform. In this blog, we will explain the comparison between AngularJS and ReactJS. By reading, you would be able to know which framework is useful for developing a web application.



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

DOM MANIPULATION:

ReactJS:

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. ReactJS is all about components.

AngularJS:

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


LIBRARY COMPATIBILITY

ReactJS:

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

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 one-way data binding approach so, the data flows only in uni-direction that makes the work easier. It makes very easy for the developers to debug the process having large 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 adequate and easy way to build component trees. With the help of functional programming language, it makes component definition 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 initialised by the controller and then transformed into HTML to create the view for the user. By using many services provided by AngularJS such as controllers, factories, directives, we can easily break code into several files.


EVENT HANDLERS

ReactJS

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

AngularJS

In AngularJS, event handlers are typically assigned to many portions of your view via directives. Directives are used for making AngularJS great. AngularJS uses ng-click directive that can be placed on HTML element which hooks up a click handler that previously exists 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 then React creates a virtual DOM and matches it with the previously saved DOM. It sends only unmatched data on the server and optimises the performance of the server while avoiding replicating data.

AngularJS

AngularJS creates a watcher for each binding for changing any value in the DOM. It relates the new value with the initial value 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, then ReactJS is good because of the concept of virtual DOM whereas AngularJS performs low. If we talk about coding purpose, then AngularJS is good as developers need to write less code here.

ReactJS is search engine optimisation friendly and compatible with heavy traffic. On the other hand, AngularJS offers stable development and testing along with reliability. Thus, we can say that it is the choice of programmers which framework they want to choose to develop any web application.
