What language is the browser plug-in written in?

Browser plug-ins (also called extensions) are typically written in the following languages:

Front-end languages:

• JavaScript (JS): Used to create interactive features of the plug-in, such as buttons, menus, and pop-ups.
• HTML: Used to define the user interface layout and content of the plug-in.
• CSS: Used to set the style and appearance of the plug-in.

Backend language:

• C: Used to write low-level code that interacts directly with the browser, such as Native Messaging API.
• Rust: Used to write high-performance, safe code, increasingly popular.
• WebAssembly (WASM): A low-level language compiled to the web for efficient execution in the browser.

Other languages:

• Python: Can be used to script and automate tasks for plugins.
• Java: Can be used to create browser-independent plug-ins, but requires a Java Runtime Environment (JRE).

Factors for choosing a language:

The following factors need to be considered when choosing a language:

• Complexity of the plugin
• Performance requirements
• Security considerations
• Maintainability and scalability
