+// ESM Exports
+// ===========
+// This module is the package entry point for ES module users. In other words,
+// it is the module they are interfacing with when they import from the whole
+// package instead of from a submodule, like this:
+//
+// ```js
+// import { map } from 'underscore';
+// ```
+//
+// The difference with `./index-default`, which is the package entry point for
+// CommonJS, AMD and UMD users, is purely technical. In ES modules, named and
+// default exports are considered to be siblings, so when you have a default
+// export, its properties are not automatically available as named exports. For
+// this reason, we re-export the named exports in addition to providing the same
+// default export as in `./index-default`.
+export { default } from './index-default.js';
