Documentation

The following functions are currently implemented:

• head: Returns the first element of an array.
• tail: Returns every element of an array except for the first element.
• middle: Returns the middle most element(s) of an array.
• map: Takes in an array and will implement a callback function on each element of the aray.
• takeUntil: Will keep collecting items from a provided array until the callback provided returns a truthy value.
• without: Returns a subset of a given aray, removing unwanted elements.
• letterPositions: Will return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue: Will take in an object and a value, scan the object for the input value and return the first key which contains the value.
• findKey: Will take in an object and a callback and scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• eqObjects: Will take in two objects and returns a boolean based on a perfect match.
• eqArrays: Will take in two arrays and will return a boolean value based on a perfect match.
• countOnly: Will be given an array and an object, and return an object containing counts of everything that the input object listed.
• countLetters: Will take in a string sentence and return an object of the count of each letter in that sentence.
• assertObjectsEqual: Will take in two objects and console.log a message based on a match or not.
• assertEqual: Will compare two values and console log a message based on a match or not.
• assertArraysEqual: Will take in two arrays and console log a message after evaluating if they are equal.
