How to find missing numbers in array?

Question

Need some logics to find this

Answer 1

One solution could be to have two arrays and loop over the expected numbers.

a = [1,2,3,4,5]
b = [1,2,5]
missing = []

foreach number in a {
if number not in array b {
add to missing array;
}
}

console.log(missing);

This is not full javascript but I hope it helps :)
