One of the most common uses of a random engine is to create a random link out of a predetermined group of links. We specify in advance the URL's to be put in "black box", and have the random engine randomly draw one out to follow.

function randomlink(){
    window.open(randomlinks[Math.floor(Math.random()*randomlinks.length)]);
}

Math.random() returns a random number between 0 (inclusive), and 1 (exclusive).

Math.random() always returns a number lower than 1.`

Math.random() used with Math.floor() multiplied with randomlinks.length() can be used to return random integers.

Using those as indexes of the randomlinks[] can be used to point to that link stored in that index of the Array.

The button has an onclick event of randomlink() function, which when clicked by the user takes him/her to that link generated randomly.

Just have some fun while clicking through various websites and enjoy the unpredictability of a mere thing, as feeble as a button.

After all a wise man once said:

The world is so unpredictable. Things happen suddenly, unexpectedly. We want to feel we are in control of our own existence. In some ways we are, in some ways we're not. We are ruled by the forces of chance and coincidence.
