If you're looking to manipulate URLs, one useful tool you can utilize is the JavaScript Window Location.

The window.location object allows you to access the current page's address or URL.

This object has various properties and methods, some of which include:

  • window.location.href - returns the URL of the current page

  • window.location.hostname - returns the domain name of the web host

  • window.location.pathname - returns the path and filename of the current page

  • window.location.protocol - returns the web protocol used (http: or https:)

  • window.location.assign() - loads a new document

For example:

To display the current page's URL:

<script>
    alert(window.location.href);
</script>
