Language/Type: JavaScript objects
Author: Melissa Hovik (on 2018/10/22)

Write a function named wordCounts that takes an array of Strings as a parameter and returns an object mapping each string to its frequency count in the array. For example, if the following array is defined: 

let words = ["To", "be", "or", "not", "to", "be"];

the call wordCount(words) should return the following:

{ "To" : 1, "be" : 2, "or" : 1, "not" : 1, "to" : 1 }

Return the empty object {} if the passed array is empty. You may assume the passed array contains only string values.

Function: Write a JavaScript function as described, not a complete program.
