It’s a no brainer that programming and web development services are the pinnacle of any business- small or big, that help in increasing product knowledge and popularity while maintaining communication between you and the potential clients. From e-commerce websites, food ordering mobile apps, digital marketing, to cloud computing; web development is an integral part of all businesses.
The list of programming languages and frameworks is extensive which makes it confusing to choose the best for your projects.
Angular and React, both lead the pack in terms of popularity amongst developers. But before deciding which out of the two is better? Let’s see why they are the popular in the first place.
What is Angular?
Angular (also known as Angular 2) is a TypeScript based open-source web application framework led by Google.
As of now, Angular 2, represents the collection of all the versions of Angular released after AngularJS. It has a complete tool kit to build large applications, which we will explore later in the article.
Some of the global leading multinational companies that use Angular are:
- Microsoft Office Home
What is React?
Some of the global leading multinational companies that use React are:
Although both are good for web development, it’s time to settle the frequent debate of React vs. Angular once and for all!
Through years of serving a global clientele as a leading mobile app development company, our developers at Communication Crafts are used to working with both; React and Angular. Using our expertise and years of experience, we can help you choose the better out of the two.
In the technological aspects, let us see the difference between React and Angular, in the following order:
1. Data Binding
Data binding, as it sounds, is connecting data from both, business logic and UI with each other.
For example – If a person using a web app word processor wants to change the colour of a certain text, he can select it from the drop-down menu feature on the app; from the available options (connection of backend to User Interface). There are many types of data binding techniques. What is interesting is the approach Angular and React take to it.
Data Binding in Angular
Angular uses two-way data binding. It synchronizes the data continuously from view to the component and vice versa. Change in either would trigger the other.
Data Binding in React
But React uses one-way data binding, in which information flows in only one direction. From data source to the UI. This helps make the code more stable and also makes debugging an app build with React much easier.
But, the two-way binding of Angular is simpler to work with.
2. Performance & DOM
React or Angular both are great for front-end development of large scale applications.
But what is DOM?
Documented Object Model (DOM), allows access to the user to change the structure, content and layout of their application. But both are not quite the same. One primary difference between both makes all the difference.
Angular 2 uses Real DOM which is a complex process to use!
Consider a case where you want to change your home address. What Real DOM would do is – update the whole tree structure of HTML tables until the desired data is reached. In this case, it is ‘home address’. Now that would make Angular a time-consuming process.
While React uses Virtual DOM (having the same properties as Real DOM) that allows updating the changes the user wants to make without rewriting the entire HTML code virtually! It makes updates faster and ensures faster performance regardless of the size of the app! Manipulating the Virtual DOM is faster than Real DOM as nothing gets drawn on the user screen.
On average, React completes a task in 3289ms compared to Angular taking 3295ms. That doesn’t seem like a lot, but in computing, it makes a huge difference in processing speed!
Which is why React wins this round.
Contrary to other frameworks and User Interface libraries available. React doesn’t oblige to a rigid architecture like the rest. Behind the interface, there are React components that are combined together to form a well-functioning UI.
But here is the thing, a React component can hold a data state(data storage of other components that is needed to make the app work), however not necessary! Each component is independent and reusable throughout the application while having little or no knowledge about the other components in the application.
But React does need some outside help! It cannot function without multiple integrations and supporting tools while working with larger applications. Some of the main ones are:
Now Angular is a complete rigid architecture model, written in TypeScript that uses its libraries to import into an application for implementation of apps functionalities.
Some of which are:
• RxJS ( library for reactive programming to compose asynchronous or callback-based code easily)
• Angular CLI ( Powerful command-line interface)
• Angular Universal (Used in server-side rendering)
Both Angular and React have a friendly environment to work with. React is easier to understand, but needs multiple integrations to achieve its maximum potential while Angular doesn’t!
As React is a library, you can integrate it into any given project, even if the project is written in Angular!
When choosing React or Angular, keep in mind the future scope of your project. React relies heavily on third-party tools, even for scaling of your apps.
Yet a sustainable architecture with server-side rendering can be easily developed with React. Which is why Facebook, WhatsApp, and Instagram which scale to a large extent; all use React!
On the other hand, Angular consists of all the main features that developers may need for scaling an existing app by adding new functionality. It is very easy to scale due to its design and command-line interface (CLI).
5. Bundle Size
You may think does size even matter in programming?
Well, it does! The smaller the size of the file, the faster it can process and load. The faster the loading speed, better the performance hence higher is the conversion rate.
Angular (766KB size) is larger than React, resulting in longer load times and slower performance on mobile.
While React (97.5KB size) is smaller than Angular, hence faster!
On the contrary, in server-side rendering, all of the HTML content is there in the source code itself. Which means search engine can crawl and index faster. This in turn offers favourable ranking in search results.
React or Angular are both server-side oriented.
But which is better in React or Angular?
React is proven for better SEO performance as it is a library for building UI. It doesn’t bother the user, the way Angular does!
Angular needs to use additional tools for SEO such as PhantomJS to tackle SEO issues. But this increases more workload for the developers, as they have to create an additional AngularJS module for SEO, link it to PhantomJS to present an HTML snapshot to the search engine for SEO. Although the updated versions have significantly reduced the performance gap!
7. Backward Compatibility
An application needs to be regularly updated.
The difference between React and Angular is that React has full backward compatibility. Being a library in itself, it’s easier for React to update its previous releases with new ones.
As for Angular, you will have to go through the hassle of updating to a newer version in Angular before you can even begin to make any changes! So if you have plans to add new features to your app as you go on, React is suitable for you!
8. Learning Curve
No one likes learning to be that difficult a process! But if you are working with Angular, you have no other choice but to endure what comes your way. Having a rigid architecture makes it more complex to work with. If that wasn’t a problem enough, it has irrelevant syntax and components that need to be managed.
9. Popularity Among Developers
According to the Stack Overflow survey I’ve just mentioned, more developers said they choose React over Angular: 31.3% of React.js vs. 30.7% Angular.
According to insights provided by, stateofjs.com. Which took a survey of approx. 21,000 people show us that:
71.7% of developers had used to React before and would happily use it again. Out of which, 16,099(89.3%) users were satisfied. That’s quite a majority!
While Angular trailed React by quite a margin! In fact only 35.8% had used Angular before and would want to use it again. Only 11,582 users (37.95%) were quite satisfied.
Clearly React is the favorite among the developers.
