This Babel preset is designed for Node.js 6.x, providing polyfills for the ~7% of ES6/ES2015 features not natively supported by V8 v5.x. It optimizes build and execution times by complementing existing V8-native functionality rather than transpiling features Node 6 can already handle efficiently. The preset is ideal for developers working with Node.js 6.x who want to use modern ES6/ES2015 syntax while maintaining optimal performance.
