Math.random[] used with Math.floor[] can be used to return random integers.
There is no such thing as JavaScript integers.

A Proper Random Function
As you can see from the examples above, it might be a good idea to create a proper random function to use for all random integer purposes.
This JavaScript function always returns a random number between min [included] and max [excluded]:
Example
function getRndInteger[min, max] {
return Math.floor[Math.random[] * [max - min] ] + min;
}
Try it Yourself »
This JavaScript function always returns a random number between min and max [both included]:
Example
function getRndInteger[min, max] {
return Math.floor[Math.random[] * [max - min + 1] ] + min;
}
