Documentation

The following functions are currently implemented:

• countLetters(): the function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.

• countOnly(): this function should take in a collection of items and return counts for a specific subset of those items.

• findKey(): function that takes in an object and callback and returns the first key that meets the criteria specified in callback.

• findKeyByValue(): function that takes in an object and a value and returns the first key that corresponds to that value.

• flatten(): function that takes in an array that contains elements including nested array of elements and returns a flattened version of the array.

• head(): the function returns the first value from the array but returns undefined if the array is empty.

• letterPositions(): function that takes in a string and returns all indices of letter positions in the string.

• map(): function that takes in an array and a callback and returns a new array based on the results of the callback on each item in the array.

• middle(): the function returns an array with only the middle elements of the provided array. If Arrays with one or two elements, there is no middle, return an empty array.

• tail(): the function returns last element of the array but returns an empty array if the array has one or less item.
