Odd, the ones I use all have tests, thousands of downloads, and active bug trackers. If I reinvented the wheel, or copy pasted, I wouldn't get those things.

Doing a for loop is not equal to re-inventing the wheel.

Words and phrases have lost their meaning nowadays.

By the JS community's standards if I wanted code to capitalize the 3rd or sometimes 4th letters of a string, they would be 2 different npm modules.

Maybe they didn't forget how to program, as the article implies; maybe they never knew how to program in the first place.

    Writing your own solution, when you could use a common widely known solution, exactly matches both writing your own left pad and inventing your own wheel.

    If there was, it would have been published and people would be depending on it. Instead, people use the stdlib first, then big lego bricks like underscore, then (when they don't want the bulk of big lego bricks) smaller lego bricks. A single capitaliseMap() might be in there but it's a much more specific case than padding.

      A 1-line of code module matches your needs exactly just for today. When you have 100 such modules which don't quite work and don't quite need after a month(quite a long time for a JS project to exist untouched), then your dependency hell shows its ugly head.

      If you had years of experience in a wide array of technologies and languages, you'd be aware of that which is, and has been, obvious to the rest of us for the past 2-3 decades.

      But surely the really concerning part is despite their very wide usage, these dependecies turned out in some cases to be poorly coded functions indeed. Throughout this whole thread are examples where these one or two line "modules" have poor runtime performance, miss key cases in the one single thing they claim to do, and in the very worst cases, those small "modules" themselves are depending on many more "modules".

      Diseases turtles all the way down.

The OP's example ( is-positive-integer) has tests, and is only three lines long, and is on major release version 3.X, because despite all that, it had serious problems in versions 1 and 2.
