 ### toHash
 
-Reduces a given iterable type into a value hash(Object by reference) by the given property or the current iteration
+Reduces a given Array Like into a value hash(keyed data store)
+
+Given an Iterable or Array like structure we 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 ) =>
-  object.reduce( ( acc, data, index ) => ( ( acc[ data[ key || index ] ] = data ), acc ), {} )
+  Array.prototype.reduce.call( object, ( acc, data, index ) => ( ( acc[ !key ? index : data[ key ] ] = data ), acc ), {} ) )
