I did it as a test task. Given a set of integers S and a positive integer L, create a function that generates all the possible subsets of S of length L. Example: if S={1, 2, 3} and L=2, then subsets(S, L) is {1, 2}, {1, 3}, {2, 3}.
function range(n) {
list = [];
for (var i = 0; i < n; i++) {
list[i] = i;
}
return list;
}
