To find a random number between 0 and (X-1), use:
Math.floor((Math.random() % 1) * X)
These are particularly useful for finding a random array element.
To find a random number between 1 and X, use:
Math.ceiling((Math.random() % 1) * X)
Tasks like this that are fairly common but require quite a bit of typing are good candidates for being turned into a function.
