Hence, let’s move on to the technical aspects and understand a clear comparison between React vs Angular.

Detailed Comparison: React vs Angular

The major differences between React and Angular depend on several parameters. Let’s discuss them individually.

Popularity

While talking about Angular vs React popularity, React tops in the popularity in terms of searches as per Google Trends. Moreover, as per a 2022 Statista survey, React has secured the second spot in the list of most used web frameworks among developers worldwide.

Angular is preferred by developers and users because of its ready-made solutions, yet both technologies are evolving. Hence, both front end development frameworks are popular and famous in the industry.

Data Binding

Talking about data binding, Angular uses two-way data binding. It means that whenever any interface element changes, the model state also changes automatically.

On the other hand, React uses one-way data binding, which renders the modifications in the interface model only once the model state is updated first. And whenever the UI components get changed, the model state remains the same without any changes.

In fact, the data flow in one-way data binding is unidirectional, which gives React developers more control over the web and mobile apps.

Components

The Angular framework consists of three components: Models, Views, and Controllers. However, the app structure of Angular is fixed and complex. Angular enables developers to divide codes into individual files, making it easier to reuse templates and codebases in other projects.

While talking about React, it doesn’t have any fixed format for writing codes. It has a very well-structured and readable codebase. The use of component trees allows the code to be logically organized. Functional programming is used in the library, making component declarations declarative.

UI Components

Angular supports a variety of material design components, such as layouts, buttons, and pop-ups. This enables a smooth and quick UI configuration.

In React, to use the material design components available, you must first install Material-UI Library and Dependencies. Developed by the community, these UI tools offer many UI components (free and paid options).

DOM

The Document Object Model (DOM) is a graph that represents a user's current browser view. Expert web developers edit the DOM to change what users view, but these changes are costly in terms of performance. As a result, both frameworks strive to reduce the cost of these operations by improving how the DOM re-renders the view after an update.

To be honest, both frameworks rely on DOM. Angular uses a real DOM, whereas React uses a virtual DOM. The entire tree structure is updated when a change is performed in Angular. Angular solves this drawback by using change detection to find components that require changes. On the other hand, React can make changes to a single element without having to update the entire tree structure by using a virtual DOM.

Tools

As we can see, Angular differs from React in terms of features. React also relies more on a state management library. In this regard, frameworks like Helmet, Redux, and React Router can help to optimize state management, API interaction, and routing.

On the other hand, Angular does not require any external libraries and has various functionalities in its package (such as data binding, project building, and component-based routing). However, it can increase its features with the help of state management frameworks (such as NgRx and RxJS).

Performance

Since Virtual DOM trees are built on the server and are quite lightweight, React looks to exceed Angular in terms of runtime performance. Furthermore, the data-binding process in React is unidirectional, which means that bindings are not allocated watchers, reducing workload.

With Angular, this is not the case. Since it uses a bidirectional data binding process, each binding requires a watcher to monitor changes, and each loop continues until all watchers (and their values) have been confirmed. As a result, the bidirectional data binding process may harm Angular's performance. However, this may change with the inclusion and enhancement of new technology Ivy to Angular.

Directives

In React, logic, and templates are explained at the end of the component. It enables the reader to grasp the meaning of the code quickly, even if they are not aware of the syntax.

In Angular, each template contains an attribute that specifies how the object should be set. The syntax of Angular directives is complex, making it confusing to a reader who is unfamiliar with the technology.

Component Architecture

Both React and Angular have a component-based architecture. As a result, they have reusable, modular, and cohesive elements. However, the difference between Angular and React can be noticed in the technology stack.

React architecture uses JavaScript, whereas Angular uses TypeScript for error-free and concise web application development.

Language

Angular uses TypeScript, a superset of JavaScript. In TypeScript, typos can be found easily, and the code is easy to navigate as well.

React can be written in JavaScript ES6+ with JSX script, which is a syntax extension that makes JavaScript code look exactly like HTML. React can be enhanced using a code translation tool to compile JSX code in a browser (e.g. Babel). Furthermore, React can be developed in TypeScript, but it is not natively supported.

React JS vs Angular: When to Choose What?
