Targeting versions

If you do not need to support older browsers, you can pick a subset of ES versions to target. For example, if you don't support pre-ES5 browsers, you can start your shims with ES2015 by requiring/importing the specific target file. This will shim the environment for that version and upward.

import 'arcadia-js-shims/target/es2015';
