To get the URL of the page you're currently on, JavaScript offers the Location interface that is exposed by the global Window object by your browser.

And you can access the Location interface with:

    
      window.location
    
  

And since Window is a global object in the browser, you can access it using this also:

    
      location
    
  

And if you want the href of the current page, use this:

    
      location.href
      // "https://coderrocketfuel.com/article/get-the-url-of-the-current-page-using-javascript"
    
  

There are also a ton of other useful properties in the location object.

Here are some examples for the page you are currently on:

    
      location.protocol  // "https:"
      location.host      // "coderrocketfuel.com"
      location.hostname  // "coderrocketfuel.com"
      location.port      // ""
      location.pathname  // "/article/get-the-url-of-the-current-page-using-javascript"
      location.origin    // "https://coderrocketfuel.com"
    
  

You can read more about both the Window and Location interfaces on the Mozilla Developer Web Docs.
