Google Chrome is a web browser developed by Google that is built using a combination of several programming languages and technologies.
The rendering engine used by Chrome is called Blink, which is a fork of the WebKit rendering engine used by Apple's Safari browser. Blink is primarily written in C++, with some components written in other languages such as JavaScript and Python.
The user interface of Chrome is primarily built using web technologies such as HTML, CSS, and JavaScript. The browser's user interface is built using the Chromium Embedded Framework (CEF), which allows for the integration of web technologies into desktop applications.
Chrome also includes a built-in JavaScript engine called V8, which is written in C++ and is designed to execute JavaScript code efficiently. V8 is also used by other applications, such as the Node.js JavaScript runtime.
Additionally, Google Chrome includes support for a variety of web technologies and standards, including HTML5, CSS3, and WebAssembly, among others.
Overall, the development of Google Chrome involves a complex set of technologies and languages, with C++, JavaScript, HTML, and CSS serving as some of the primary building blocks for the web browser.
