+***(Nov 2022) Important Update:** This library has been redesigned to support **Golang Generics**, and it is not backwards 
+compatible with the previous version. Also requires at least Go 1.18. If you require the older version without generics

+without generics by running the following command:*

 ##### Quick Overview
 
 Streams facilitate operations on arrays, iterables and collections, such as *filtering*, *sorting*, *mapping*, *foreach*, and parallel operations on the items contained by these arrays, iterables or collections
