testing tree-shaking with rollup and webpack2

Each folder contains a build.sh file whcih should be ran to compare output of rollup vs webpack2. I have included the dist files so that there is no need to download and run the commands to see the differences.

dependency-local-with-es2015

Demonstrates the the use of local dependencies on es2015 modules.

import {cube} from './poor-math-skills';

Results

• Rollup pulls in only the functions required
• Webpack pulls in only the functions required

import {cube} from 'poor-math-skills';
// vs
import {cube} from 'poor-math-skills/ecm';
