Most js build systems don't do dead code removal. This ends up encouraging many small packages instead of bundling functionality into larger packages. For example, there is a lodash package, but people don't want to include the whole thing, so now there is one package for each function: https://www.npmjs.com/~jdalton https://www.npmjs.com/~jdalton As far as I know this aspect is unique to nodejs/npm.
