Angular VS ReactJs in the Front End Development World

When it comes to front-end development Angular and ReactJs are considered to be the top two technologies. But to choose between the two is one of the most confusing decisions as both of them have their advantages. Angular and ReactJs both solve frontend development problems but in their own ways. 

Merely sometimes back it was enough for the business to have a website inorder to reach their broader market. But today statistics have shown a huge increase in the types of business websites that are being consumed by the audiences for better interaction with the brand. 

So, the debate between ReactJs and Angular has been an ongoing one. Since both are coming up with new versions every year and also brining in great features, so the decision to select one has become very difficult. 

A brief on ReactJs and Angular 

About ReactJs

ReactJs is an interactive user interface, meaning it is a necessary element of the frontend development of applications. It is a library that you can use to determine how your application is going to look to your users and how they can operate and interact with it. In other words, as per the Model-View-Controller framework, ReactJS creates the upfront view of the website. 

About Angular

In regard with ReactJs, Angular is a complete framework that is built on TypeScript that has the capability to spin code efficiently. It is a wholesome toolkit that has everything to build an entire application or website. 

ReactJs Vs Angular – Showing the difference between the two 

  1. Underlying Architecture 

ReactJs is a Model-View-Controller (MVC) framework with a rendering UI library, that means it uses written code or JSX to create the interface. Biggest advantage is that it does not force on the architecture of your apps and allows you a great deal of freedom during the development process.

Whereas Angular, is a complete MVC that can develop an entire architecture of a website or an app. The little limitation it carries on with it is that it offers minimal flexibility, meaning unlike ReactJs you cannot add functions on the developed architecture making it limited within the scoop of the tools. 

  1. Components 

These are one of the USPs of Angular and ReactJs. Components are the small chunks of codes that can be added to add a specific functionality. But both of these technologies have a very clear distinction in them such as –

ReactJs has a number of free as well as paid UI components that can easily add functionalities to your app or website. Also, these components can be built using JavaScripts. One of the biggest advantage of building your frontend with ReactJs is that it has community that keeps on adding new chunks of code which can be used by anyone.  

Unlike React, Angular doesn’t only imbibe components even though it follows a component-based approach, Angular is a complete framework that can help you easily develop modern, reactive, and component-driven frontend of an application or a website. Which implies that Angular offers more options than developing components which includes such as validations, routing, state management, form, and lots to develop large applications.

  1. Performance 

This is one of the major aspect, analyzing the impact of technology on the performance. 

Document Object Model is the factor that decides the performance. DOM is a programming interface that makes the browser read the object and nodes in applications’ XML or HTML documents. And both Angular and ReactJs maintain their DOM very differently. 

ReactJs is considered to have an edge over Angular but only in its certain respects. Such as the virtual DOM allows its apps to virtually update the changes without rewriting the entire HTML document. This renders updates much quicker, allowing lightning-fast performance regardless of the size of the application, making it great in terms of scalability. 

Whereas, Angular being the complete framework of frontend development in its regular DOM feature makes the application slow in performance. This is the reason that Angular is ideal for developing single-page applications that only updates a single view at a time. 

This way Angular presents lower performance with large and complex multi-faceted applications. However, Angular has Change Detection technique to optimize performance.

  1. Templates 

In ReactJs, templates are called JavaScript XML or JSX, which combines the JavaScript code and markup in one line of code this helps in developing user interfaces efficiently. It is an extension to JavaScriptthat makes use of HTML-like syntax where you can build components by combining code and markup.

On the other hand, Angular uses advance HTML that has Angular ng-if ng-or directives. This indicates that you have to properly learn to code in advanced HTML to code the frontend correctly.  

  1. Data binding 

ReactJs and Angular both has components to render UI. Things to consider when using ReactJs or Angular is their component’s logic that has all the data related to a component that gets displayed in the User Interface. So, the connection between data and the component’s logic is data-binding. 

React has only one way of data binding which means that the model state is updated and then it renders changes to the user interface. But if you change the UI that doesn’t mean that the model state will also change. For that you will have to figure out so ways such as state management libraries or callbacks. 

Whereas in Angular there is two way of data binding that means if you change the UI then the model state will also change and if you change the model state then the user interface will also change. This gives an added advantage to Angular as compared to ReactJs. 

  1. Dependency Injection

It has been seen that certain dependency injection is almost indispensable in data-binding. This is because some of them helps with decoupling where there is no additional data layering in the application model. 

This is a problem in the ReactJs technology as Dependency injection (DI) goes against current architecture of functional programming and immutability. 

But in Angular dependency injection makes it capable of creating different lifecycles of different stores. This implies that the stores creates space for the components mount that makes them smoothly and limitlessly available to components’ children.  

In ReactJs the language makes use of global app state that maps different components but this way you will be introducing bugs when cleaning component unmount. 

Websites that are Built on Angular and ReactJs 

Forbes which is one of the world’s most visited websites is built on Angular. The website has the capacity to respond to more than 74 million queries on a monthly basis in the United States alone. Angular has given the website the authority to work on reusable codebase, provides uninterrupted user experience, and also the support and maintenance are easy. 

Example of ReactJs is supreme Facebook, the website is built on React Library and its products. Facebook developers use React to create responsive UI. React and also maintain high website performance. Lately, Facebook has supported 2.45 billion monthly active users and this number is continuously growing. 

To Conclude 

So, before you kickstart your frontend development it is important that you keep these aspects in your mind. With these it is also necessary for you to know that the learning curve of these two technologies are very different. As ReactJs is JavaScript programming language, it is way easier to work on this language because of its simple design, detailed documentation, libraries, and JSX. In contrast with ReactJs, Angular is complex and developer needs to learn the syntax. But once there is a hand on syntax the technology gives multiple options to solve a single problem.
