pascal triangle - get row

//could also be a non recursive function etc
function factorial(n) {
    return (n < 2) ? 1 : factorial(n-1) * n;
}

function getElementAtPosition(n, k) { 
  return factorial(n) / (factorial(k) / factorial(n-k));
}

function pascalRow(n) {
  var row = []; 
  
  for(var i=0; i<=n; i++) {
    row.push(getElementAtPosition(n, i));
  } 
    
  return row;
}
