Style nit: two more spaces of indent.
When loading a module, Node needs to finds the end of a shebang comment by searching for a \r or \n character. This behaviour is now standardized into a dedicated internal module function Refs: nodejs#12180

You could just drop the if (contLen === 2) case, it should almost never be hit.

stripHashBang() would be clearer

Shebang is more commonly used. For example, the Hashbang article on Wikipedia redirects to the Shebang article.

As a single data point: I've been a UNIX user for 20+ years and this is the first time I've heard someone call it a hashbang.

does this lint? I would expect a space after 35

Yes it does. This code originates from lib/module.js (see master branch)

The implementation looks good to me, but I think this should have a regression test for the issue in #12180. |

Ping @seppevs – do you think you could add a test here? or, the other way around: @not-an-aardvark would you be okay with landing this and keeping #12180 open until we have a test? It would seem like an acceptable second or slightly adventurous first contribution for next week’s Code & Learn. |
Sounds good to me. |
