Answer 2

Use a function and pass the array as the parameter... Then apply indexOf method to find the missing number. Take a look at this to understand what I'm trying to say:

x = [1,2,3...100];

function missingNumber(x){
for(var i=1; i<=x.length; i++){
if(x.indexOf(i) == - 1){
return i
}

That's what you need ( one of the thousands way to achieve it) Good luck dude.
