The following functions are currently implemented:

• assertArraysEqual: Takes in two arrays and prints an appropriate message to the console.
• assertEqual: Checks if both input and output have a perfect match.
• head: : Returns the element at the 0th index of the given array.
• tail: Returns the rest of the array after removing the element at the 0th index.
• middle: Returns the middle element of an array.
• map: Returns a new array based on the results of the callback function.
• assertObjectsEqual: Detects if two objects are equal.
• countLetters: Returns a count of each of the letters in a given sentence.
• countOnly: Takes in an array and an object, and returns an object containing counts of everything listed in the input object.
• eqArrays: Takes in two arrays and returns true or false based on a perfect match.
• eqObjects: Takes in two objects and returns true or false based on a perfect match.
• findKey: Takes in an object and a callback function, and returns the first key for which the callback returns a truthy value. If no key is found, it returns undefined.
• findKeyByValue: Takes in an object and a value, and returns the key associated with that value.
• letterPositions: Returns all the indices (zero-based positions) in a string where each character is found.
• takeUntil: Returns a slice of the array with elements taken from the beginning
• without: Returns a new array with only those elements from the source that are not present in the itemsToRemove array.
