Angular vs React: Which Should You Choose? | SF AppWorks

Before diving into the Angular vs React debate, let's start with defining them. Angular is a full framework, but React performs faster and boasts a much larger transfer size. 


While both Angular and React have their benefits and challenges, React tends to be preferred by industry professionals. Read below to figure out the differences between Angular and React, and how to know which one is better for you.

What is Angular?


Angular is a framework written in TypeScript. Google developed the JavaScript framework in 2016. Google's Angular Team and the Angular developer community are responsible for maintenance. 


What is React?


Facebook developed React in 2013 as a Javascript library to use when creating apps. Facebook still maintains it today with an open-source community of developers. 


Angular vs React: Architecture Differences 


There are some core architectural differences between Angular and React that can help you gain a better understanding of their uses. 


Check out SF AppWorks for help building mobile and desktop web apps from beginning to end.


Library vs. Framework


Angular is considered a full-fledged framework. This is because it offers you guidelines on how to structure your app. When using Angular, you don't need to decide on libraries to route to. However, this creates a huge drawback; you can only use what Angular provides.

Angular offers:

  • Templates
  • XSS protection
  • Dependency injection
  • Ajax requests
  • Routing
  • CSS encapsulation
  • Utilities to test components
  • Angular forms


React enables you to have more freedom. All it provides you is a "view" in MVC. Therefore, you can choose any library that fits your needs. The biggest drawback is that you need to take care of updates and migrations on your own. While React may seem to create more room for error, this problem can be easily overcome by consulting or working with an experienced app design company. By telling an experienced developer your needs, they can leverage the flexibility of React to design your app the way you like.


React offers:

  • JSX language built on top of JavaScript
  • XSS protection
  • No dependency injection
  • Fetch for Ajax requests
  • Utilities to test components

Regular DOM vs. Virtual Dom


React uses virtual Dom, which makes it very fast. Why is this?

When you want to update your app, a virtual Dom looks at the difference between the previous and current HTMLs. Then, it simply changes whatever needs to be updated. 


Angular uses a regular DOM instead. This doesn't compare the HTML differences. Instead, it updates the entire HTML tree structure.


App speed is a crucial component of user experience. The app will slow down considerably if there are a lot of change requests on a single page.

React took a gamble and decided to combine both UI templates and inline JavaScript logic. This is JSX, and no one had ever done anything like it before.


This innovative concept paid off in a big way. It offers a huge advantage during the app development process. This is because you have the markup, logic, and language all in the same place. The end result? Code completion and compile-time checks work smoothly.

One Way Vs Two Way Binding


Data binding is the term used for the synchronization process between the model and the UI view.


React uses one-way binding. The model state updates, then renders the change in the UI element. However, if you want to change the UI element, the model state won't change automatically. This gives you better control for each step of the process.


Angular uses two-way binding. Regardless if you change the UI element or the model, the other will change along with it. This can make it easier to debug your app, but it means that you have less manual control.

TypeScript vs. JavaScript/Flow


If you want to use Angular, you'll need to use TypeScript. This is a statically typed language. This means you need to define every variable's string, number, array, etc. As a result, this can bog down an app's code.


React, on the other hand, uses JavaScript. This is a dynamic language, so you don't need to define a variable's type. You can also use Flow to enable type checking in your React project. JavaScript is easier to use and read, plus, it minimizes turnaround time.

App Development


Angular incorporates the ability to use Ionic for developing hybrid mobile apps. It provides a robust UI component library. This makes it straightforward to set up mobile apps.


Since Facebook created React, its platform is native mobile friendly. React creates a truly native UI. Even if React may seem more complicated to use, the payoff is usually worth it. And, once again, you won’t have to worry about the nuances of using React during the development process by teaming up with a great app development company.


Web Development


When it comes to web apps, you can still use Ionic to develop. However, the result is a web app inside of a web view container. This can make the app lag and slow down for the user if you choose Angular.

Facebook uses Jest to test code within React. It doesn't require any configuration and provides a powerful mock library. You can also use Jest with Enzyme. 

To test Angular code, you can use Jasmine. The result is many options you need to sift through. It can provide useful solutions, but it can also be very difficult to read.

Examples of Use


You can find real-life examples of both React and Angular, which are some of the biggest companies in the world. Here are a few examples: 


  • Facebook
  • Airbnb
  • Uber
  • Netflix
  • Instagram
  • WhatsApp
  • Dropbox


  • Google
  • Nike
  • Forbes
  • Upwork
  • General Motors




React is pure JavaScript logic. Even though it doesn't work with DOM, it's still popular, even in DOM based libraries. 


React can be used in both web and mobile development. For mobile development, though, you need to incorporate Cordova. You can also use React to build single and multi-page web apps.


Angular is a little less compatible. This is due to it requiring Typescript and type definitions for every library you use.


You can use Angular to create both web and mobile apps. However, when you use it for mobile apps, a lot of the work is done by Ionic. Angular can also be used for single and multi-page web apps.

Angular is pretty easy to scale. This is due to its design and powerful CLI (Command Line Interface). 


React is also easy to scale because of its testability. Since React uses a virtual DOM and a React library, it can look into further scalable development. It's a great way to build reusable and scalable components.

Here's an infographic on Angular vs React comparison:

angular vs react infographic




Currently, Angular has 40,963 stars and 732 contributors. The flip side is that it has 2,162 issues. On average, Angular gets 35 stars a day.


On the other hand, React has 111,927 stars and 1,242 contributors. Since it's only a view library, it has far less issues than Angular (only 287). React also gets about 97 stars a day. 


React is becoming the most popular in full stack and millennial communities. It's a great choice for native JavaScript mobile and desktop apps.

Angular vs React: Which is Right for You?


Both React and Angular are useful, but React is preferred when it comes to flexibility, speed, and control. However, here is a useful list to consider:

  • Are you a passionate developer? React will probably let you have more freedom in creativity.
  • Are you a start up? Go with React.
  • Do you like to use templates? Angular would be a better choice.
  • Do you like JavaScript? Go with React.
  • Do you like more flexibility? Use React.
  • Are you partial to object-oriented programming? Angular would probably be better for you.


Comparing Angular and React · Conclusion


Angular is a full-fledged framework that will help you with every step of development. React is a framework for UI development that lets you incorporate your own libraries. It can turn into a full-fledged solution with more flexibility to fit your needs.


React seems like a simpler option and the best one when it comes to creating mobile-friendly apps. It does take a shorter time to start your work. That being said, you will have to learn how to use other frameworks and tools to complete a project. This won’t get in the way, though, if you use an expert team of app developers.
