React vs. Angular: What’s the Difference?

Understanding the differences between Angular and React is paramount in web development. Both frameworks boast their own strengths, making them widely adopted by industry professionals.

On the one hand, Angular is a full-fledged framework offering many features and adhering to an MVC architecture. On the other hand, React is a lightweight library focused on rendering view layer content through components-based architecture.

However, by exploring their differences, developers can make well-informed choices and select the framework that meets both project requirements and personal development preferences. Here are the main differences between the two frameworks.


Angular is a TypeScript-based framework. Generally, TypeScript is an extension of JavaScript that adds static typing for improved tooling and compile-time error checking. It provides features like type checking, interfaces, classes, and modules suited for large-scale projects.

Nevertheless, TypeScript’s strong typing allows for better code maintainability and helps developers detect problems early during development. Unfortunately, learning TypeScript may present greater difficulties for developers unfamiliar with static typing.

angular vs. react
Angular uses a hierarchy of components as its primary architectural characteristic.

On the other hand, React is a JavaScript library, and developers can take advantage of its flexibility and simplicity in building user interfaces. As JavaScript is widely-used and well-established, its ecosystem offers plenty of libraries and resources that support React development.

Fortunately, React is widely adopted, making it easy for developers to start working with it quickly and find community support.


On the one hand, Angular features a comprehensive JavaScript framework technology that offers an all-inclusive solution for building web apps using various technologies like TypeScript, HTML5, and CSS. Additionally, it adopts a Model View Controller architectural pattern that provides for opinionated and structured development.

Specifically, it features dependency injection, two-way data binding, dependency injection, and robust libraries and tools. Its built-in features and extensive technology make it fit for large enterprise apps with complex needs and requirements.

On the other hand, React is a JavaScript library technology built for the view layer of applications. It uses JavaScript and syntax extension JSX rendering components on user interface pages.

In addition, its component-based architecture allows developers to build reusable and modular UI components. Plus, having React’s technology stack primarily revolving around related ecosystems makes it more flexible than Angular.

Front-End Development Approach

Angular enhances HTML functionality through additional directives and components. It uses a template-driven approach where HTML templates are directly bound to components, and developers are enabled to craft dynamic and engaging user experiences.

Additionally, Angular favors client-side rendering, whereby rendering occurs within the browser. Furthermore, this rendering option features an engaging user experience with real-time updates and interactivity on the client side.

On the other hand, React uses a JavaScript library approach with component-oriented development in mind. Plus, it introduces an XML-like syntax, JSX, allowing developers to write HTML-style code inside JavaScript.

React favors server-side rendering, wherein initial rendering occurs on the server before sending to clients. Consequently, it enhances performance and enhances search engine optimization (SEO).

Document Object Model (DOM)

Angular’s Real DOM approach ensures any changes directly impact the DOM structure. This status, therefore, means the entire DOM tree gets updated.

Consequently, it could significantly affect performance when dealing with complex and large-scale applications. Real DOM allows for more accurate representations of user interface (UI), yet may be resource-intensive and lead to slower rendering times.

React can be used to develop single-page, mobile, or server-rendered applications.

On the other hand, React employs the Virtual DOM approach, creating a lightweight copy of the DOM. Additionally, React updates the Virtual DOM in case of changes, then efficiently determines the minimum number of updates needed to synchronize its real DOM with its virtual representation.

This selective update process greatly decreases the number of manipulations necessary on an actual DOM, improving performance and rendering speed.

Dependency Injection

Angular provides built-in support for dependency injection, offering a reliable and comprehensive DI system. Additionally, developers can centrally define dependencies and resolve them during component instantiation.

Angular’s DI provides many advantages, including code modularity, easier maintenance, and testability. However, by decoupling components and services, Angular facilitates improved code organization and reuse of components.

On the other hand, React does not support dependency injection. It doesn’t provide a dedicated DI system, yet allows developers to implement DI patterns using third-party libraries or custom solutions.

Furthermore, React’s approach to managing dependencies is more flexible, leaving developers to select their desired DI implementation. Specifically, developers now have more freedom than ever to use the DI libraries or design patterns of their choice.

Preferred Data Flow

Angular supports two-way data binding, enabling automatic data synchronization between model and view. Accordingly, changes made to a model will automatically reflect in its view without needing explicit updates.

Additionally, two-way data binding simplifies development by minimizing the code necessary for synchronization. However, they can add complexity and make it challenging to keep track of changes and determine the source of updates.

React, on the other hand, promotes one-way data flow or unidirectional data flow. Here, data flows top-down through props from parent components to child components.

Furthermore, child components cannot directly modify data received as props. Instead, they emit events or invoke callbacks to trigger updates in their parent component.

Fortunately, one-way data flow provides greater predictability and simplifies debugging changes, making comprehending how data moves through an application more straightforward.
