JS Digger is a web browser extension that lets you see all the JavaScript functions and variables on a webpage.

Once you have installed the extension, you can browse and modify JavaScript functions, objects, and variables on any webpage you visit by going to "Inspect" in the Chrome Dev Tools.

You can search through the functions by using the search box, filter the results by using the filtering tools (class, id, and data), and you can also refresh the results to see the changes.

You can browse the JavaScript functions by typing in the search box or by using the search function in the function menu.
