lodash vs underscore size comprasion

Readme.md

In reply to Jeremy's tweet, that underscore is 3x smaller (simpler?) than Lodash! https://twitter.com/jashkenas/status/568564455937839106

Apparently, it's only true if you use <script> tag, but if you use lodash's module feature and build your project with browserify(or webpack) you get different numbers. In simple cases underscore can be 4-6 times bigger.

 1647 bundle-lodash-without.min.js.gz
13032 bundle-lodash.js

 1854 bundle-lodash.min.js.gz
51951 bundle-underscore.js
25045 bundle-underscore.min.js
 7093 bundle-underscore.min.js.gz

Build commands:

browserify lodash.js -o bundle.lodash.js
uglifyjs bundle.lodash.js -o bundle.lodash.min.js
gzip -c -- bundle-lodash.min.js > bundle-lodash.min.js.gz

lodash-without.js

var without = require('lodash.without');
console.log(without([1, 2, 3, 4], 3));

lodash.js

var without = require('lodash/array/without');
console.log(without([1, 2, 3, 4], 3));

undrescore.js

var _ = require('underscore');
console.log(_.without([1, 2, 3, 4], 3));

Using lodash-webpack-plugin the size is ~1Kb.
The _.without method is a little more involved than your inline snippet and more flexible/reusable.
