Angular vs React Which to Choose for Your Front End

What is Angular?
Angular is a development platform and application-design framework built on TypeScript with component-based architecture for building scalable web apps. It has a collection of well-integrated libraries and features, such as client-server communication, routing, and more, that help speed up front-end development. It also has a suite of developer tools to develop and scale projects from single-developer size to enterprise-grade applications.

Angular is a complete rewrite of AngularJS (no longer maintained) from the same Google engineers’ team. However, Angular is constantly updated and is backed by a massive community of developers.

Here are the distinctive features of Angular that set it apart from React:

Two-way data binding
Dependency injection
Virtual scrolling
Angular CLI

Angular vs. React: A quick comparison
React and Angular are popular JS frameworks for building complex and interactive web applications. While they share several similarities, some distinct characteristics make them fundamentally different. Let’s compare the two frameworks briefly before discussing the technical aspects in detail.

Angular React
Type  Full-fledged structural framework JavaScript-based library
Purpose Develop dynamic web apps  Build interactive UI components
Language  TypeScript  JavaScript (JSX script)
Developed and maintained by Google  Meta and community
Front-end development approach  Extends the functionality of HTML, prefers client-side rendering  Uses XML-like syntax called JSX, slight preference for server-side rendering
DOM Real  Virtual
Performance High  Relatively high (since virtual DOM renders updates much faster & ensures fast runtime performance)
Dynamic UI binding  UI binding at plain object or property level  Direct linking of states to the UI
App structure Fixed and complex platform, component-based framework Flexible, component-based
Data binding  Two-way One-way
Dependency injection  Supports dependency injection, allowing for separate lifecycles for different stores  Does not fully enable dependency injection, because each component has its own global state
Learning curve  Can be steep for beginners  Relatively small
GitHub stars  86.7k 203k
Ideal use cases Develop complex enterprise apps, progressive and single-page web apps and websites  Modern and large web apps with frequently variable data, natively-rendered hybrid apps for Android and iOS devices
Detailed comparison: Angular vs React
Let’s now compare React and Angular in detail.

Popularity: Angular vs React
Both frameworks have gained popularity in discussion forums and the developers’ community. But which is more popular? While looking at popular stats, Angular has 86.7k stars, and React has 203k stars on GitHub. And according to a Statista survey in 2022 on the most used web frameworks worldwide, React secured the second spot while Angular was in the fifth spot.

Angular: Since its initial release as AngularJS in the early 2010s, it gained a lot of popularity, especially for building single-page applications. Thus, it is a mature framework.

In 2016, Angular 2 was released, a complete redesign of AngularJS, with many new features and improvements. Since then, Angular has continued to evolve and improve with new releases and remains a popular choice for building web apps. However, competition from other JS frameworks and libraries like Vue.js (a progressive framework) and React has affected its popularity.

React: React is the clear winner here as it has always maintained more popularity on average than Angular. It gives the advantage of rendering optimizations, virtual DOM, and easy migration between versions. Moreover, it has the simplest ways to reuse the UI components, offering an easy way to get tasks done. All these and more features of React have made it the go-to JS front-end framework for dynamic web applications.

Performance: Angular vs React
Both frameworks have distinct abilities to build high-performing web apps. But which is faster? While React has quite a good reputation for boosting performance, Angular isn’t lagging anywhere in the competition.

Angular: Angular has everything to optimize coding practices and leads to an established level of programming that continually enhances performance. For example, optimizing the digest cycle for your proposed code structure is easier with Angular. While you develop the codebase for further modules, monitoring and optimizing the loop can verify the previously assessed changes.

Also, projects that don’t need two-way data binding can be served with older versions of Angular to reduce complexities to a noticeable extent. Moreover, Angular offers $cacheFactory that works better for memorization and can eventually be used for recalculating the data being calculated later. And in terms of rendering of pages, Angular uses real DOM but has a unique mechanism of change detection combined with zones that makes web apps faster.

React: React boasts of a virtual DOM, one of its most sought-after features for application performance. It allows front-end developers to make changes without having to rewrite the full HTML document. This ensures speedier performance by rendering updates faster and refreshing data faster on web pages.

The reusability of components is another aspect of React that gives it a competitive edge. It can be a critical issue when your developers working on different projects are dealing with complex logic and cannot reuse it again in the projects. React can solve this issue by allowing developers to reuse system components.

Reusing React components is also common among designers since it doubles the productivity and optimizes coding practices – starting from the finest components like the checkbox and the button, moving to the wrapper components, and reaching the root components. Such practices ultimately lead to consistent app performance and facilitate code quality and maintenance regardless of the project’s complexity.

Data binding: Angular vs React
The biggest difference between Angular and React lies in state management. React depends more on state management libraries such as Helmet and React Router. Angular has built-in data-binding, whereas Redux library usually augments React to provide unidirectional data flow and work with immutable data. Which is better?

Angular: Angular uses two-way data binding, meaning that the model state changes automatically whenever any interface element changes. This keeps the two layers updated with the same data.

Angular binds the HTML element to the model variable and not just displays it but also changes it in the backend. It helps coordinate the two data models of a framework, which helps create an interactive user interface without the programmer’s intervention of several callbacks and extra efforts.

Two-way data binding is the most efficient technique for fetching data from large ERP-based software like medical software, accounting, and other software that demands highly complex requirements. Thus, Angular’s bidirectional nature makes it easy to build ERP software.

React: It uses one-way data binding, which renders the modifications in the interface model only after the model state has been updated first. And whenever the UI components get changed, the model state remains the same without any changes. This unidirectional data flow gives React developers more control over the web and mobile apps.

React library does not follow the automatic approach to data binding and lets developers fall into the nitty-gritty of complex handling of objects. However, it uses one-way data binding with two-way data binding helpers to manage heavy parsing work and extensive data manipulation.

Code quality and maintainability: Angular vs React
Angular: At Simform, we leverage tools like AngularCLI to scaffold, build, and maintain high-performing Angular applications. Moreover, integrations like Angular Core, Angular Material, etc. have made our Angular project deliveries more effective and code quality better.
