The following functions are currently implemented:

• anagram: Returns true if the two strings are anagrams of each other.
• calculateDayInYear: Calculates the day of the year for a particular date string. Words on leap years.
• conditionalSum: Returns the sum of the numbers in the array if the condition is true. Conditions can either be 'even' or 'odd'.
• countLetters: Takes in a sentence(string) and returns a count of each letters in the sentence.
• countOnly: Returns an object with a count of each element in the input array.
• eqArrays: Compares two arrays and returns true if they are equal. Returns false otherwise.
• eqObjects: Compares two objects and returns true if they are equal. Returns false otherwise.
• findKey: Returns the first key for which the callback returns a truthy value in an object.
• findKeyByValue: Returns the first key that matches a given value in an object.
• flatten: Nested arrays will be flattened into a single array.
• head: Returns the first element of an array.
• join: Joins all elements of an array into a string.
• letterPositions: Takes in a sentence(string) and returns an object with each letter as a key and the index of the letter in the sentence as the value.
• map: Takes in an array and a callback and returns a new array with the results of the callback applied to each element.
• middle: Returns the middle number in an array. If no middle element is present, returns the average of the two middle elements. Only works on arrays of integers.
• palindrome: Returns true if the input string is a palindrome. Returns false otherwise. Works on strings containing capitals, lower cases, and spaces.
• pigLatin: Takes in a string and returns a Pig Latin version of the string. Rules of Pig Latin here.
• tail : Returns the last element of an array.
• takeUntil: Takes in an array and a callback and returns an array with the elements of the array until the callback returns a truthy value.
• without: Takes in an array and a value and returns an array with all the elements that do not match the value.
