In this article, we're going to take a closer look at two of such tools: Angular and React. Read on to find out what they are, how they differ from one another, what benefits they bring to the development process, and what their essential pros and cons are.
Ready to learn which of these technologies is a better pick for your project? Let's dive in!
What is React?
Who uses React? Apart from Facebook, the technology has been used by Netflix, Asana, Slack, Uber, Airbnb, Dropbox, Instagram, and WhatsApp.
What is Angular?
Note that both of these web frameworks are open-source and available under the MIT license.
Who uses Angular? Among the most significant users of the framework, we find brands like the already mentioned Google, Upwork, Paypal, Crunchbase, AWS, Nike, Forbes, General Motors, and HBO.
How popular are React and Angular?
When choosing the technology stack for your project, you should consider the popularity of the framework or library you're going to pick. The reason is job prospects. The more popular a technology is, the more experts you'll be able to find. Popular programming languages and tools are surrounded by active communities that help to solve problems and continuously work on perfecting these technologies.
In general, React is growing faster than Angular. Have a look at npmtrends.com, a service that compares package download counts over time. You'll see that the download numbers of both Angular and React are rather steady, but React has many more downloads. The scale is also reflected on GitHub, where React has amassed over 133k stars, while Angular got only 59600.
React vs. Angular: Comparison
Features: Framework vs. library
Angular is a framework because it suggests how applications should be structured and offers plenty of functionalities out-of-the-box. Developers don't need to decide which libraries to use; they can just start coding. But with that comes less flexibility
Here's what Angular provides out of the box:
- Templates (based on an extended version of HTML)
- Dependency injection
- Component CSS encapsulation
- XSS protection
- Ajax requests
- Utilities for unit-testing components
- Form building
React is a library and so it gives developers more freedom in structuring their applications. It provides the view in MVC, leaving the M and C to be solved by development teams. If you choose React, your team will be able to pick their preferred libraries – but note that you'll also be responsible for managing updates and migrations. Expect to make some decisions regarding folder hierarchy and architecture as well – and they sometimes present a risk to application development.
Here's what React provides out of the box:
- JSX instead of classic templates
- XSS protection
- Fetch for Ajax requests
- No dependency injection
- Utilities for unit-testing components
- You can easily add functionalities like state management, routing, and testing utilities using
Another area worth considering is the learning curve involved in mastering a given technology. It determines the availability of experts in the field.
According to Stack Overflow's 2018 Developer Survey, React is the 2nd most loved technology and Angular managed to score only the 9th place.
Now let's take a look at another side of that survey – the most dreaded technologies. While Angular scored relatively high, at the 4th position, React is located lower, at 11th. Developers may find Angular challenging to work with. And when we turn to the last section showing the technologies developers want to learn the most, we see that React occupies the 1st position. Still, Angular managed to score the 4th place, which isn't that bad.
React is more flexible, but it imposes a lot of decision-making on the team. For example, developers can choose from 16 different packages for state management alone. But that means debugging is easier because developers don't need to look at the entire code, just their own. Many React developers never read the library source code – simply because they can get away with that and still build a well-functioning app. The same is not true for Angular, where developers often have to debug the framework internally to understand the underlying model properly.
- The idea behind Angular's creation is that it would be used alongside Typescript – and that's why the framework offers outstanding support for it.
- Developers can take advantage of the Angular-language-service, allowing intelligence and autocomplete inside component-external HTML template files.
- Angular is continually developed and offers a host of new features – for example, one of the recently added features was the possibility to generate and develop WebComponents based on Angular.
- The framework offers detailed documentation to help developers get the hang of its many features. However, the extensive nature of Angular documentation also results in a steeper learning curve. Education and training are often time-consuming.
- Angular offers one-way data-binding that allows for singular behaviour for the app. That minimizes the risk of developers making errors and keeps the development process smooth.
- The MVVM (Model-View-ViewModel) allows individual developers to work separately on the same app section, using the same dataset.
- Angular offers a structure and architecture that favour project scalability.
- Angular offers a great variety of structures (for example, Injectables, Components, and Pipes). That makes it harder to learn for developers – especially in comparison with React that has only Components.
- Potentially slower performance. Angular developers usually deal with that by taking advantage of the ChangeDetectionStrategy that allows manual control of the rendering process.
- React has a gentle learning curve thanks to its detailed documentation, simple design, and the use of JSX (which has an HTML-like syntax).
- React also accelerates the development process thanks to its Virtual DOM implementation and different rendering optimizations.
- The library offers outstanding support for server-side rendering. That way, React can be treated as a powerful tool for content-focused applications.
- React also supports Progressive Web App (PWA) development. It offers the `create-react-app` application generator that helps developers create such apps in no time.
- Developers who are skilled in React can apply their knowledge to mobile development (React Native).
- It leaves developers to make many choices which require strong project leadership.
- Some developers find mixing templates with JSX logic confusing.
Angular and React have gained a strong following because they offer excellent performance and top development speed. We hope that this comparison helps you make the best technology choice for your application.
