41. Consider the following code snippet
function printArray(a)
{
var len = a.length, i = 0;
if (len == 0)
console.log("Empty Array");
else
{
do
{
console.log(a[i]);
} while (++i < len);
}
}
What does the above code result?
function printArray(a)
{
var len = a.length, i = 0;
if (len == 0)
console.log("Empty Array");
else
{
do
{
console.log(a[i]);
} while (++i < len);
}

{
if (spam>a == 1)
continue;
else
a++;
