Aside, the size of the NPM database ... is that really indicative of the amount of JS code out there? For example, how many trivial modules like "isarray" are there, whose sole active code is this single line?

     return Object.prototype.toString.call(arr) == '[object Array]';

Is npm really the largest codebase, larger than PyPI, Maven and Ruby Gems?

On a more subjective level, does npm solve more nontrivial problems than any other programming language repository?
