jQuery Loop Dynamic variable generation

Question

I have a list of arrays received from PHP response.[1], response.[2], response.[3], ... etc. I want in jQuery Loop create these variables and alert them. but I get this error in Console "bill is not defined"

var i;
for (i = 1; i < 4; ++i) {
  var bill[i] = response[i].sum;
  alert(bill[i]);
}

@ZakariaAcharki I tried that too 'var bill1 = response[1].sum;' — A.K.

You could use window[] that will define the variable globally or you could use eval() like :

var response = [{
  sum: 0
}, {
  sum: 11
}, {
  sum: 22
}, {
  sum: 33
}];

for (var i = 1; i < 4; ++i) {
  window['bill_' + i] = response[i].sum;
  //console.log(window['bill_' + i]);
}

for (var i = 1; i < 4; ++i) {
  console.log(window['bill_' + i]);
}

Is there a specific reason to not implement it with the fix in your comment?

After reading the question another time I have noticed that the author says create these variables and alert them
