Node 5.x brings ~59% native ES6/ES2015 coverage. This preset for Babel 6 attempts to bridge the gap for the much of the remaining 41% using Babel plug-ins.
Babel 6.x is awesome, but simply including the ES2015 preset means you're transpiling features that your Node 5.x installation can already do faster and natively, replacing them with inferior / old code.
This preset complements existing V8-native functionality - it doesn't work around it.
The end result is nearly always a faster build and script execution time.
