Lodash is a good example of this. The whole package is pretty big, and includes a functional programming variant (which I suppose is mostly wrappers around the other stuff, but it still adds weight). So in practice you'll pretty much never be using the full package on account of 1) going for either require('lodash') or require('lodash/fp'), but not both, and 2) requiring specific functions through require('lodash/each') or whatnot. The only way to get an accurate picture is to analyse the bundled package, or I suppose as part of the pipeline of whatever packaging solution you use.
