Answer 1

In first loop you print <i> value then you increment <i> value.

In second loop you increment <i> value, then you print <i> value.

Answer 2

Coder In the first condition
After the document.write i is incrementing that's why it starts printing 8 to till 19

In the second condition
After the while condition i is incrementing that's why it starts with 9 ends with 20
