• head: A function to extract the first element of an array.
• tail: A function to extract the subarray not containing the first element.
• middle: A function to extract the middle element(s) of an array.
• assertArraysEqual: An assertion function to check if 2 arrays are equal.
• assertObjectsEqual: An assertion function to check if 2 objects are equal.
• assertEqual: An assertion function to check if 2 primitive data types are equal.
• countLetters: A function to count the number of letters in a string.
• eqArrays : A function to check if 2 arrays are equal.
• eqObjects: A function to check if 2 objects are equal.
• findKey: A function to search an object and check if a given key exists.
• findKeyByValue: A function to find the key of an object that is equal to the input value.
• flatten: A function that takes in a array of nested arrays and forms a new array of a single layer, made up of all the elements from the nested arrays.
• letterPositions: A function that takes in a string and outputs an object consisting of subarrays for all the positions of each letter in the given string.
• map: A function that takes in an array and a function and transforms every element in the given array by the input function.
• takeUntil: A function that takes in an array and a callback function and outputs a new array constisting of the elements of the original array until the callback function acting on the original array returns a truthy value.
