// So the problem was that we are declaring function inside
// for loop, which has variable i that is global for inner function because it is declared as var.
// So everytime we create a function, the variable i is changed,
// and eveytime the i changes, the funciton is keeping last value.

// As a solution we can declare i as let, so that it will be local variable and everytime,
// i changes old value will be kept
