There was a problem hiding this comment.
Note: The .slice() method supports negative indices, which count positions from the end of the string.
For example, str.slice(-3) returns the substring containing last three characters from str.

Thanks for the review. Updated the PR description with the learners template, simplified displayHour to one line, and used slice(-2) for minutes. All 9 tests still pass. |
