The following functions are currently implemented:

• head: Returns the first item of an array.
• tail: Returns all except the first item of an array.
• middle: Returns the middle item/s of an array.
• assertArraysEqual: Assert equal function that works for arrays.
• assertObjectsEqual: Assert equal function that works for objects.
• assertEqual: Assert equal function for primitive data types.
• countLetters: Counts the number of characters in a string.
• eqArrays: Returns true or false based on whether two arrays are identical.
• eqObjects: Returns true or false based on whether two arrays are identical.
• findKey: Takes in an object and a callback and returns the first key for which the callback returns a truthy value.
• findKeyByValue: Takes in an object and a value, it will scan the object and return the first key which contains the given value.
• flatten: Takes in an array that may contain nested arrays and returns an array without nesting.
• letterPositions: Take in a string and return an object where the position of each character is stored.
• map: Maps the elements from one array to another based on a provided callback function.
• takeUntil: Populates a new array with elements from an existing array until a truthy value is returned by the callback function.
