Documentation

The following functions are currently implemented:

• head: Returns the first item in an array.
• tail: Returns all items in an array with the first item removed.
• middle: Returns the middle item in an array if the length of the array is odd. Returns the two middle items in an array if the length of the array is even.
• countLetters: Takes in a string and returns an object with the count of each letter in the string.
• countOnly: Takes in a collection of items and return counts for a specific subset of those items.
• eqArrays: Compares two arrays, returning true if they are matching and false if not.
• eqObjects: Compares two objects, returning true if they are matching and false if not.
• findKey: Takes in an object and a callback function, and returns the first key in the object for which the callback returns a truthy value.
• findKeyByValue: Takes in an object and a value, and returns a specific key in the object that matches the value
• letterPositions: Takes in a string and returns an object where each letter is a key and each letter's index is the corresponding value.
• map: Takes in an array and a callback function, and returns a new array based on the results of the callback function.
• minimumValues: Returns the smallest number in an array.
• takeUntil: Takes in an array and a callback function, and returns a new array with all items starting from the index 0 until the callback function returns true.
• without: Returns a subset of a given array, removing unwanted elements.
