Documentation

The following functions are currently implemented:

• head(array): returns the first item in the array. If the array is empty then retun undefined.
• tail(array): returns the "tail" of an array: everything except for the first item (head) of the provided array.
• middle(array): return middle item(s) as array of given array.
• without(array, remove): return a subset of a given array, removing unwanted elements.
• countOnly(allItems, itemsToCount): will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• countLetters(string): return a count of each of the letters in given string.
• letterPositions(sentence): return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue(object, value): return a key on an object where its value matches a given value.
• map(array, callback): return a new array based on the results of the callback function.
• takeUntil(array, callback): return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• findKey(object, callback): return the first key for which the callback returns a truthy value.
