In this blog, we will discuss the comparison between Angular JS and React JS. In the next few minutes, you will be reading about what separates Angular and React from each other and which framework we should choose for developing any application.
React uses one-way data binding, so, data can flow only in one direction. Because of this, it’s always clear where the data was changed. The process of one-way data binding in React keeps complexity under control. It’s much easier to debug self-contained components.
To implement a unidirectional data in React, Facebook created its own application architecture called Flux through one control point called the dispatcher. The dispatcher of Flux receives an action and transfers it to an appropriate store, which then updates itself. After finishing the updates, the View changes itself and sends a new action to the dispatcher. Thus, we can say that Flux is beneficial to update the data dynamically.
Data binding in AngularJS is the automatic synchronization of data between the view components and the model. AngularJS uses two-way data binding process so it allows a user to write less code. It connects the Document Object Model (DOM) values to Model data through the Controller. It means, if the user provides a new value to the app then there is view and model both are updated. Its drawback in two-way binding is its negative impact on the performance.
AngularJS relies on two-way data binding, this makes our AngularJS application laggy. As we know, AngularJS creates a watcher for each binding to track changes in the DOM. It compares the new value with the initial value runs the $digest loop after the view updates. The $digest loop then checks actual changed values and the values tracked by the watchers. During development, we may come to a point when an app is packed with too many watchers for bound elements, the performance will decrease.
As we know, AngularJS applies changes in the real DOM in the browser. So, whenever the real DOM gets changed, the browser also has to change many internal values to represent a new DOM. This also decreases the application performance.
AngularJS is based on Model, Controller, and View thus it is complex and addresses single page application development. For AngularJS development object is responsible for Model Part, which is initialized by the Controller and then transformed into HTML to create the view for the user. It works with MVC and provides a reliable solution for development projects. AngularJS provides many standard services, directives, controllers, factories, etc. With AngularJS, we can break code into several files.
To conclude, both AngularJS and React are great for writing single-page applications. But they are completely different from each other. Some programmers say ReactJS is better while some say AngularJS for AngularJS development. But, it depends on your project and choice as both have some specialties.
ReactJS is real time, compatible with heavy traffic, and search engine optimization friendly. On the other hand, AngularJS offers smooth development and testing along with reliability. However, working with ReactJS seems to be easier but it also depends on your project. Both are great for single- page writing.
