Why Large Tech Companies Use React

7 min readJul 5, 2023


As digital experiences continue to shape global business, the right technologies are critical in delivering high-quality, seamless, and user-friendly applications. One such technology, currently at the forefront of web development, is React, a JavaScript library for building user interfaces. React’s use by tech titans like Facebook, Instagram, Airbnb, and Netflix is a testament to its efficiency and robustness, making it a preferred choice for large-scale projects. This article takes an in-depth look at the reasons large tech companies opt for React, focusing on its impressive features and explaining why this framework is a great choice for large-scale tech teams.

1. Embracing Component-Based Architecture

React is popularized for its innovative approach to structuring web applications — the component-based architecture. This architecture fundamentally alters how web development is approached by fragmenting the user interface into individual components. Each component in React is responsible for rendering a small, reusable piece of HTML, which can be nested within other components to build up complex user interfaces. This philosophy presents several benefits:

Reusability and Efficiency

The component-based architecture promotes code reusability. Components are written once and reused across different parts of the application, significantly reducing the amount of code written and the potential for errors. This leads to reduced development time and, consequently, cost savings.

Separation of Concerns

By dividing the UI into separate components, developers can isolate specific functionality within each component. This leads to better separation of concerns, making the codebase easier to manage and debug. Each component can be thought of as a self-contained unit that can be independently developed, tested, and understood.

Team Collaboration

For large tech companies managing complex projects with numerous developers, this architecture is a boon. Developers can work concurrently on different components without impacting each other’s work. This leads to increased productivity and faster product development.
