Script Preparation code:

var arr = [];
for (var i = 0; i < 12345; i++) {
  arr[i] = i;
}

function someFn(i) {
  return (i * 3 * 8 / 1200 * 0.002 / 40 * 0.2);
}

map
arr.map(item => { if(item == 123) { return item * 2; } return item; });
for
var hung = [] for (var j = 0; j < arr.length; j++) { if(arr[j] == 123) { hung[j] = arr[j] * 2; } hung[j] = arr[j]; }
