> By relying on these small rigorously tested libraries they are avoiding the need to test their own code, and thus avoiding basic null check or conversion errors.
In practice, many, if not most, of these one-line modules don't even work correctly, and it is difficult to get people to care to collaborate on fixing them instead of just replacing them with a new one-line module that works slightly better as the concept of complex collaboration to perfect one line of code is so foreign to a generation of developers who would rather just throw code to the world and never look back (an issue made all the worse as tiny bugs in these one-liners can almost seem dangerous to fix when you aren't really sure how they are being used: maybe it actually is better to not fix anything and just have people rely on the replacement better module :/).
