Underscore.js is a utility-belt library for JavaScript that provides support for the usual functional suspects (each, map, reduce, filter...) without extending any core JavaScript objects. It's available in ES6 and UMD (cjs, amd, iife) formats

ES6 & Beyond usage:

• partial importation of features (just call the function's name prefixed by _).

(nb: only _chain isn't available in this case)

import {_template} from 'underscore-es';

var basicTemplate = _template("Ok, i use <%= builder %> for my es6 and beyond stuff !");
var result = basicTemplate({builder: 'rollup'});
console.log( result ); 
// => "Ok, i use rollup for my es6 and beyond stuff !"

• global importation of all features

import _ from 'underscore-es';

_.chain([4,7])
 .union([7,0,3])
 .initial()
 .reverse()
 .head()
 .value()
 // => 0

• breaking changes

Since this underscore source code has been rewritten to be more es6 friendly, the _.templateSettings property is now _.template.settings and the _.iteratee shall now (for global importation) be overwritten through _.setIteratee([fn]) method.
