The philosophy was kinda refreshing in the early days. There was a really low barrier to publishing and people were encouraged to build and share tools rather than hoard things. It was probably somewhat responsible for the success of npm and the node ecosystem, especially given the paltry standard lib.

Of course, like most things, when taken to an extreme it becomes absurd and you end up with isOdd.

I think the issue is that the JavaScript ecosystem is so large that even the strangest extremes manage to survive. Even if they resonate with just 0.1% of developers, that’s still a lot of developers.

The added problem with the atomic approach is that it makes it very easy for these fringes to spread throughout the ecosystem. Mostly through carelessness, and transitive dependencies.
