for loop with call
var sum = 0;
var keys = Object.keys(obj);

function call(x){
  sum = sum + keys[x];
}

for(var x = 0; x < 100; x++){
  call(x);
}
ready
for loop without call
var sum = 0;
var keys = Object.keys(obj);

for(var x = 0; x < 100; x++){
  sum = sum + keys[x];
}
ready
another for loop without call
var sum = 0;
var keys = Object.keys(obj);

for(var x = 0; 100 > x; x++){
  sum += keys[x];
}
