Which file extension corresponds to JavaScript files?

JavaScript files use the .js file extension. This designation helps web browsers and developers quickly identify files that contain JavaScript code, which is a scripting language used to create and manage dynamic content on websites. The .js extension indicates to the browser that the file should be interpreted as JavaScript, enabling it to execute the script properly.

In contrast, the other extensions pertain to different technologies: .java is used for Java programming language files, .php corresponds to PHP files which are server-side scripting files, and .html is used for HTML files, which mark up the structure of web pages. Each of these file types serves distinct purposes in web development, but .js specifically identifies files that include JavaScript code.
