Warning: Unidentified JavaScript alert(notification) encountered without declaring a

Imagine this scenario - when I type the following command:

open google.com

I need JavaScript to detect "open google.com" and prompt me with an alert. The challenge is figuring out how to generate an alert for just "google.com" without including "open".

var varopen = "open";
if (result.match(varopen)) {
    alert(result);
}

My goal here is to only display the value of "result" and not include "varopen".

Essentially, I'm looking for a way to make alert(result - varopen) function correctly, even though my knowledge of JavaScript is limited.
