Usage notes
就是…… is used to express "even if" in case of a hypothetical statement. This construction is the same as ……也, ……也, ……也, ……也 and ……也. There are differences with the last two: 就算 gives a feeling that the hypothesis has little chance of being realized, while 哪怕 is stronger.

If the statement is not hypothetical, …… is used instead.

Interjection

 * 1) it sure is!; exactly!
