• middle(arr): Returns the middle-most element(s) of the given array

• countLetters(sentence) : Returns an object showing the number of times each letter appears

• countOnly(allItems, itemsToCount) : Returns an object showing the number of times each element in an array appears but only for those elements that have a value of true in the itemsToCount object

• findKey(obj, cb) : Returns the first key of an object with value properties as an object that meets the condition of the callback function cb

• findKeyByValue(obj, val) : Returns the first key in an object which contains the given value

• letterPositions(sentence) : Returns an object with all the indices where each individual letter appears in the string

• map(arr, cb) : Returns a new array after performing the calculations in the callback function cb on each element

• takeUntil(array, callback) : Returns a slice of the array with elements taken from the beginning until the callback returns a truthy value

• without(source, itemsToRemove) : Returns a subset of a given array, removing unwanted elements
