-## Summary
+## Description
+
+  > Groups JavaScript objects array by a key and returns grouped array.
 
   Groups the scattered objects in an array based on a `groupByKey` (e.g. id). For the given `groupByKey` value, if there is a multiple occurrence of same key (e.g., contact key for id: 3) but with unique values, then the values will be grouped into an array.
