Explanation

The third parameter in xmlhttp.open() is a boolean that determines whether the request is asynchronous (true) or synchronous (false). When true, the request executes asynchronously and doesn't block the browser. When false, it runs synchronously and freezes the UI until complete. Asynchronous (true) is the recommended approach.
