• assertEqual: receive 2 values and print whether or not they are equal
• assertObjectsEqual: receive 2 objects and print whether or not they are equal
• countLetters: receive a string and output an object displaying how often each character occurs
• countOnly: receive an array and an object designating which items should be counted, outputs an object displaying amount of times each specified item occurs in array
• eqArrays: receive 2 arrays and output true if they are equal and false if they are not
• eqObjects: receive 2 objects and output true if they are equal and false if they are not
• findKey: receive an object and a callback function specifying desired value, outputs key found by function
• findKeyByValue: receive an object and a string representing desired value, outputs key matching value
• flatten: receive a nested array and outputs an array with one level of nesting removed
• head: receive an array and output the value at index 0
• letterPositions: receive a string and output an object with characters as keys and arrays with their indicies as values
• map: receive an array and a callback function, outputting a new array with each value in input array modified by function
