How to randomize an integer variable using JavaScript?

How can I randomize a variable in JavaScript between 0-4, so that every time the page loads the variable is different but between 0 and 4?

// Returns a random integer between min and max  
function getRandomInt(min, max)  
{  
  return Math.floor(Math.random() * (max - min + 1)) + min;  
}

You can use Math.random() for this. To get a (whole) number between 0 and 4 inclusive, use the following:

var random = Math.floor(Math.random() * 5);
