 Given an Iterable or Array-like structure, call `Array.prototype.reduce.call()` on the provided object to step over it and return an Object, keyed by the reference value.
 
 ```js
-const toHash = ( object, key ) =>
-  Array.prototype.reduce.call( object, ( acc, data, index ) => ( ( acc[ !key ? index : data[ key ] ] = data ), acc ), {} )
+const toHash = (object, key) =>
+  Array.prototype.reduce.call(
+    object,
+    (acc, data, index) => ((acc[!key ? index : data[key]] = data), acc),
+    {}
+  );
 ```
 
 ```js
-toHash([ 4,3,2,1 ]); // { 0: 4, 1: 3, 2: 2, 1: 1 }
-toHash([ { a: 'label' } ], 'a'); // { label: { a: 'label' } }
