Which is a more efficient code snippet?
Code 1 :

for(var n=10;n>=1;n--)
{
           document.writeln(n);
}

Code 2 :

var n=10;
while(n>=1)
{
       document.writeln(n);
       n++;
}

1. Code 2
2. Code 1
3. Cannot Compare
4. Both Code 1 and Code 2
5. None of these

Code 1 would be more efficient. Infact second code will go into runtime error as the value of num will never reach less than or equal to one.
