//  1. Find Highest Frequency (findHighestFreq)
//
//  Goal: find the most frequent occurrence in an array
//
//  Input: an array (<inputArr>) i.e. [2, 4, 9, 4, 2, 32, 4, 5, 2, 1]
//
//  Output: most frequent occurrence i.e. '4' in the above example
//
//  Note: if there is no winner, return 'null'

export function findHighestFreq(inputArr) {

}




//  2. Get Property Array (getPropArr)
//
//  Goal: return an array of values of a specific property from an array of objects
//
//  Input: an array of objects (<objects>), and a property string (<field>) i.e.
//
//    objects = [{id: 1, name: 'joe'}, {id: 2, name: 'tom'}, {id: 3, name: 'mike'}] 
//            
//    field   = 'name'
//
//  Output: an array of values i.e. ['joe', 'tom', 'mike'] in the above example
//
//  Note: if <objects> is undefined, return 'null'

export function getPropArr(objects, field) {

  /*<YOUR CODE HERE>*/

}




//  3. Sort Object Array (sortObjArr):
//
//  Goal: sort an object array in a particular order based on field value
//
//  Input: an array of objects (<objects>), a property string (<field>), and an <order> i.e.
//
//    'asc'  = ascending:
//              A, B, C, D (strings / alphabetically)
//              1, 2, 3, 4 (numbers or counts / numerically)
//
//    'desc' = descending: 
//              D, C, B, A
//              4, 3, 2, 1
// 
//  Output: the initial array of <objects> sorted by <field> in the appropriate <order>
//    
//    Reference './tests/mockUsers.js' for the user data structures
//
//  Note: should be able to sort objects based on the following fields:
//
//    firstName (string / alphabetically)
//    lastName (string / alphabetically)
//    email (string / alphabetically)
//    groups (count / numerically)
//    age (number / numerically)
