Angular Vs React: Which One is Best for your App in 2023?

Published On November 25th, 2022 Tech Talks

Angular and React are both powerful front-end programming languages popularly known to build modern and complex web app interfaces

In fact, a recent report by Statista claims that people use almost 1.88 billion websites. Among them 42.62% of the websites were built with React and 20.39% were built with Angular. Eventually, the usage of these frameworks are drastically increasing. 

Well, now the question is – Which language would you choose between Angular vs React?

So, in this article, we’ll dive deep into the features, budget, development time, learning curve, and benefits of these javascript programming resources to help you make an informed decision. Let’s get started!

What is Angular?

Angular or Angular 2 (formerly AngularJS) is an open-source structural framework built and maintained by Google since 2010. This framework uses TypeScript and HTML to build web apps, single-page web apps, and hybrid apps, mostly for large-scale businesses. 

Globally popular projects like Microsoft Office Home, BMW Cost Calculator for Driveaways, Xbox, Forbes and Samsung are built with Angular

What is React?

React (or Reactjs/ ReactJS) is also a front-end Javascript library developed and maintained by Meta (formerly Facebook). This framework is used by programmers to build the (UI)User Interface of their apps, from individual features to complete components. 

Above this, React library codes are reusable and have virtual DOM and JSX. As exciting as it sounds, the code drastically cuts down the development time and saves you from a huge spend. Sounds great right?

1. DOM

What is DOM?

If you need to change the structure, content and style of an HTML document, you’ll have to use Document Object Model, in short, known as DOM

This model is a programming interface which represents web pages as nodes and objects in a tree structure. This organization of the web page data lets you create, change, or remove elements in your project, as per your needs.

DOM: Angular vs React

AngularReact
Angular operates on traditional or real DOMReact uses virtual DOM
Say, you need to change your email information on the page. Angular’s real DOMs update the entire HTML table structure until it reaches the email information for changeLets you instantly access or edit the HTML document virtually. 
Causes potential issues with the performance and speed of the web pages. No matter the size of the app, virtual DOM makes React JS perform much faster than traditional DOMs. 

Eventually, due to the speed and reliability, Developers prefer React DOMs for the coding architecture over Angular. 

2. Data Binding

What is Data Binding?

How do you synchronize the UI components on the user-side to the data sources in the backend of your app? 

Well said! Data Binding does it with ease using declarative formats. 

But how each data is bound in Angular and React pretty much differs from each other in terms of performance and process. Let’s look into the differences:

Data Binding: Angular vs React

AngularReact
Angular uses both two-way data binding computations. React uses one-way binding computations.
Bi-directional or Two-way binding is an approach where a change in the UI element will correspondingly cause a change in the model’s state.Unidirectional or One-way binding is when a change is updated in the UI element, it changes affect the model state. 
Conversely, any change in the model state reciprocates an equivalent change in the UI elements. But the point is, the binding process stops here, and does NOT happen the other way around. 

While this may sound like Angular’s two-way approach is much better, it turns out that bi-directional binding throws complexities into managing the UI elements and model states, as your app scales over the years. 

On the other hand, React is preferred to be the most favorable library for larger and complex projects for its effective code management and debugging

3. Component Flow 

In order to build an app with smooth user experience, you’ll need frameworks that can sort your app’s components in an orderly fashion. 

In simple terms, you need a clear structure so that you can store the reusable components in your library and drop them into your app wherever and whenever needed. 

In this case, React and Angular differ vastly in their architectural approach.

Component Architecture: Angular vs React

AngularReact
Angular is a complete framework by itself comprising unique features. It has Angular CLI (Command Line Interface), RxJS (reactive programming with Javascript) and Angular Universal (used on the Server-side)React breaks each UI component to structure them into a more complex component to perform desired functionalities. 
Uses web components for activities like transpiling.To bring these components to complete operation, you’ll need several other integrations and support tools like Webpack (module bundler), Redux (state container) and Babel (JSX into JS transpiler).

Although React is robust, it demands multiple support integrations to perform its fullest. So, here I’ll give it to Angular. 

 
Still Hesitating Whether it is Angular or React?

4. Testing Framework

Any app or software has to be subjected to testing to verify and analyze if it does what it is built for. The founders of React and Angular use different frameworks to test each of them. 

Here’s what I got to know:

Testing: Angular vs React

AngularAngular
Google uses a framework known as Jasmine to test Angular.While Facebook tested React, it used Jest. 
Developers found this testing inflated the process and made it much more difficult to understand.This framework is easy to use and is developer-friendly since it does not require any configuration to perform its operations. 

As claimed by the developers as “delightful JavaScript testing”, with absolute clarity, let’s call it React here. 

5. Learning Ease

Would you like to learn the technologies Angular or React? While your interest to grow proficient peeks into research, you’ll need to understand that each of these languages have their distinct features

Learning Curves: Angular vs React

AngularReact
In small scale projects, Angular tends to be easy to grasp. Regardless of the project size, React seems to give difficult beginnings. 
However, in large-scale projects, Angular turns complex due to its two-way flow.But its consistency of UI and model states keep the complexity of the framework at sane levels even for larger projects.  

The unidirectional binding keeps React simple and stable throughout the project flow. So , it would be fair to call it React here. 

6. Load Time

The app load time depends on the size of the files used to construct them. These files consist of bundles which must be relatively small in size to load faster and increase the app ‘s conversion rates. React and Angular deals with the bundles sizes in different approaches, as you may find below:

Load Time: Angular vs React

AngularReact
Angular eliminates the development utilities and unused modules from the users’ app.As for React, it uses a support tool – webpack to split the code into smaller pieces of code.
It also optimizes the bundle size further by compression and minification of files.It also performs on demand code import and dead code elimination to reduce the size of each bundle in the app. 

Does it sound like a tie to you? Well it is!. Angular and React, both take the win with effective load times by bundle size reduction. 

7. Scalability

When your app grows, the technology you choose must expand accordingly. So, it is necessary to keep in mind about the scope of your project in the coming years before you arrive at a decision on your tools. 

Scalability: Angular vs React

AngularReact
Angular is a full-featured model-view-controller (MVC) framework that comes with all the essentials that developers need.As mentioned earlier, React depends heavily on third-party integrations which makes it easy to scale when your app grows.
It allows you to scale your existing app by just adding new functionalities. In fact, global giants like Facebook and whatsapp use this technology for their projects.

Its best to put to test – the stability of the architecture when the app scales. And React will win for large scale projects. 

8. Version Updates

To keep your app fresh with modern features your users expect, you need new technologies and modules. And to do this, your frameworks and libraries must be compatible for the updates and releases.

Version Updates: Angular vs React

AngularReact
When you need to make a switch from an older version to the latest one in Angular, first you need to install the updates between every version. In contrast, React has complete backward compatibility.
It is not possible to make leaps without updating to the consecutive versions.React lets you update the older versions and update different releases to enhance your project.

Without a doubt, React might be the best choice if you are looking to update your app versions instantly. 

The Final Call

Although both Angular and React lets you build professional-grade web apps, each of them have their own pros and cons based on the size of the project. 

The above comparison criteria showcases that Angular fights tough against react on small scale apps. But, React stands at the top with tons of advantages like virtual DOMs and optimizations, as mentioned in the article. Finally, with this technology, developers have an immense range of opportunities to eliminate errors and speed up development.

Frequently Asked Questions (FAQ)

How is React different from Angular?

Firstly, React is a library that uses virtual DOM & smaller bundle size while Angular is a full-fledged framework running on incremental DOM. Secondly, React.js operates on a one-way binding method meaning that any change in the UI element doesn’t alter the state of the component. This is not the same in the case of Angular which works on two-way binding tech leading to slower delivery and performance.

Angular vs React: Which is better?

While both Angular and React JS are great front-end development tools, developers prefer React over Angular because of the ease of debugging files that helps us to achieve better app stability. Plus, React JS makes use of libraries and so, we can integrate those libraries into any project even if the project is developed using Angular.

Why is React preferred than Angular?

React is said to beat Angular on factors like backward compatibility, data binding, time, cost, bundle size, and the ability to reuse components. Developers prefer to React over Angular as the former language uses one-way binding making the code stable and debugging easier. React is said to beat Angular on factors like backward compatibility, data binding, time, cost, bundle size, and the ability to reuse components.

Why is React faster than Angular?

As React uses virtual DOM, it allows devs to update changes without the need to rewrite the entire HTML doc. Thus rendering faster updates and performance. Secondly, React JS tends to split codes into smaller sections, thereby taking less time to load, gets ranked highly, and converts soon.
