I've tended to avoid both underscore and lodash because they're both in the slew of monolithic pre-npm libraries, however the lazy evaluation looks interesting. I wouldn't be surprised to find a library that handles lazy eval without all the extra features Lodash brings.
lodash offers modules for node, es6, amd, individual npm packages and bundled in the primary npm package so you can even do require('lodash/array/chunk').

#81I remember trying this a while ago and being disappointed at the amount of dependency code brought in for a rather trivial function, but the modularization is looking much better than it was last time I took a look.
