how to loop through array items multiple times

Question

So, if I wanted to log the numbers one to five once, I might write something like:

var array = [1,2,3,4,5]
function loop(n) {
 for (var i=0;i<n;i++) {
 console.log(array[i])
 }
}
loop(5)

but how would I log the numbers one to five more than once?

eg writing loop(10); to get the following result: 1 2 3 4 5 1 2 3 4 5

Obviously at the moment I get 'undefined' for anything above loop(5)

Use the remainder operator :

function loop(n) {
 for (var i=0;i<n;i++) {
 console.log(array[i%array.length])
 }
}
