How to nest loops using outer index in inner start evaluation in CoffeeScript?

How to write two nested loops in CoffeeScript: where the inner loop is using the outer loop current index as its initial value?

ie 

for (int i = 0; i < array.size(); i++) {
    for (int j = i; j < array.size; j++) {
        ...
    }
}

Thanks!

Most succinct way I could think of: 

for item, i in array    
    for item, j in array when j >= i

Try something like this, maybe:

for i in array
  for j in [i ... array.size()]
    console.log i, j
