Function

Question

The following this code will result in want value?

function test(number)
{
while(number < 5){
number++;
}
return number;
}
alert(test(2));
I wondered how can the result of this code return "5" instead of 3 cause the number is 2+1 should be 3

Answer 1

It returns 5.
In first while loop number is 2 which is less than 5
2++ = 3 -> number
Now number is 3, it enters the loop as 3<5 is true
3++ = 4 -> number
Now number is 4, it enters the loop again since 4<5 is true
4++ = 5 -> number
Now number is 5, it fails the condition in while I.e, 5<5 is false and it comes out of the loop and returns 5.
Hope it is clear.
