I ask this with genuine curiosity. I'm an outsider when it comes to js development really. A while ago a lot of discussion was made regarding libraries like jquery and frameworks made to solve common problems. Much of the argument went along as "why are you using such a big library when you are using just a tiny part of it?? Don't be lazy!" Now in the wake of leftpad issues, the most common argument I've personally observed, has been "why are you using a library that solves just this one problem? Use a library that provides the full utility around this problem area (strings)". It feels strangely contradictory but I'm most likely missing some context here. Just wondering what it is :)
