React is a widely-used, open-source JavaScript library designed to create user interfaces and single-page web applications. Developed by Facebook and released in 2013, React has become a popular choice for web development. But what language is used in React?

The primary language executed in React is JavaScript, the world’s most popular scripting language. JavaScript is a high-level, interpreted language with object-oriented capabilities that enable developers to create interactive web pages and applications. React relies on JavaScript to define the structure of user interfaces, create dynamic elements, and manage user interactions with those elements.

In addition to JavaScript, React uses other technologies such as HTML and CSS to construct user interfaces and style components. HTML is a markup language used to define the structure of web pages and apps, while CSS is a styling language used to establish the look and feel of web pages and applications. HTML is used to define the structure of user interfaces, and CSS is used to style the components.

React also utilizes JSX, a JavaScript syntax extension that allows developers to write HTML-like code within JavaScript. JSX makes it easier for developers to write React components, as it allows them to write HTML and JavaScript code together instead of separately.

In addition to JavaScript, HTML, and CSS, React also utilizes other libraries and frameworks such as Redux, GraphQL, React Native, Apollo, and React Router. These are used to create dynamic and interactive web applications.

In conclusion, React is a popular, open-source JavaScript library used to create user interfaces and single-page web applications. It utilizes JavaScript, HTML, CSS, JSX, and other libraries and frameworks to construct user interfaces and style components. With its range of languages and tools, React is a powerful and versatile library used by many developers to create dynamic and interactive web applications.
