Real. However, the same day the left-pad debacle stuff was on HN, this was changed to be self-contained: https://github.com/tjmehta/is-positive-integer/commits/maste...

"Serious problems in versions 1 and 2" suggests that it might be a good idea not to write your own version 1. But to be explicit about the history: version one[0] had dependencies. Version two[1] had no dependencies, and a comment on github suggests that it might be wrong but I can't immediately see how. Version three[2] is a different implementation, and adds another export. [0] https://github.com/tjmehta/is-positive-integer/commit/3003f9... [1] https://github.com/tjmehta/is-positive-integer/commit/b47e90... - it should return false for 0, so I'm not sure what the commenter is getting at [2] https://github.com/tjmehta/is-positive-integer/commit/3cdfe1...
