>> Regardless, any sort of environment where you can do `import extend from 'just-extend';` is going to (have a way) support map and filter. That is not true for the now-fairly-common use case that browserify/webpack satisfy. I write code with ES6 module syntax and build with browserify (& babelify) to target the browser. But I still need to pull in modules like lodash.map/lodash.filter if I want to target IE8. (I could use es5-shim but that makes for less portable code).
