React vs Angular – A Quick Comparison (2020 Update)
The possibilities are limitless, and so is the number of choices we need to make every day. And making the right choice is challenging – especially in the IT industry. In Pagepro, we want to help you make informed decisions every single time. And it’s one of the reasons our blog exists.
Today’s dilemma is choosing React vs Angular to build a web application. Let’s go through it, step-by-step.
What is React?
Pros and cons of React
Now, let’s take a look at some advantages of React from a business perspective and its cons.
|Great UX||Lack of proper documentation|
|Popularity||The high pace of development|
|Shortened time to market|
If you want to find out more, we prepared a detailed summary of React JS pros and cons, which you can read here.
Companies using React
Facebook isn’t the only company taking advantage of React and its possibilities. There are a few more well-known brands, such as:
However, it doesn’t mean that React is the right choice only for big brands – it’s on the contrary. You can use as little (or as much) of React as you need at the moment. For example, adding React to your website is literally a matter of one minute.
What is Angular?
Angular is a result of rewriting AngularJS, which was the first version of Angular.
Important note: Google won’t support AngularJS after June 30, 2021.
Pros and cons of Angular
You already have learned about React.js pros and cons, so it’s time to find out why it’s a great idea to choose Angular (or not).
|Better error handling||Huge size|

Building mobile apps: React Native vs Ionic
Choosing React allows you to use React Native to build truly native and cross-platform mobile applications. While RN uses a bit different syntax than React does, it’s relatively easy to learn it if you are already familiar with React. With React Native, you can create components and bind them in Objective-C, Java or Swift code.
Angular, on the other hand, uses Ionic, which is a hybrid mobile framework. Instead of building native mobile apps, you need to develop a web application inside a Cordova container.
When it comes to the performance of both applications, if they are well-written, the difference will be hard to notice.
Angular is using two-way data binding. Whenever you change any element of the interface, your model state changes automatically too.
It sounds simple, but if you work on a large project and want to have a good data overview and debug easier, it is better to use React with one-way data binding. It renders the change in the interface element, only after the model state is updated first. And whenever you change the UI element, the model state stays the same with no changes.
Since React is a lightweight UI library, it’s much easier to learn than Angular. A list of things you have to absorb is quite short: JSX, a router library and state management library. Also, it’s necessary to have knowledge of writing components, managing internal state and using props.
Angular is not a library – it’s a fully-fledged MVC framework. Because of that, a list of things to learn is much longer than in the case of React.js:
- Dependency Injection
And that’s just a start.
The popularity of any particular programming language or web technology can be a great source of information – especially if such popularity is measured objectively and over time. Looking at these stats will help you with gathering answers to questions like:
- Is there (and will be) demand for this technology?
- Will it be easy to find and hire developers?
- Is it something worth checking or just a waste of time?
To determine the popularity of React and Angular, I checked Github, Google Trends, and Stack Overflow Annual Survey.

Since 2019, React.js lost its first place to ASP.NET Core, but it’s still at the top. Angular, on the other hand, stayed in the middle.

React is using a virtual DOM, which means it doesn’t have to update all the HTML. He is just looking for the differences between the current and the old HTML and updating it accordingly.
Angular is using real DOM, which means it is going through the entire structure of HTML to find what there is to be changed and “mutate” the tree to apply changes.
A while ago (with v16 version) React changed its engine elevating the speed from “just fast” to “blazingly fast”.
More than that, React Fiber enables the priority-based update system, so you can fine-tune your renderings to make sure the most critical updates are done first. Also, you can pause and start your work at will.
Angular is using templates based on an extended version of HTML with Angular directives. You will also have to learn a specific syntax.
Angular uses Jasmine, which outcome is considered by many as one of the hardest to read and too complicated.
