Is Chrome Extension code the same as javascript code?

Chrome extensions are built using web technologies such as HTML, CSS, and JavaScript. Therefore, the code used to develop a Chrome extension is essentially JavaScript code, but with some additional APIs and functionalities provided by the Chrome browser.

A Chrome extension typically consists of a manifest file and one or more JavaScript files. The manifest file defines various properties of the extension, such as its name, version, and permissions required. The JavaScript files contain the logic and functionality of the extension.

In other words, the code used to develop a Chrome extension is JavaScript code, but with some additional APIs and functionalities provided by the Chrome browser.
