Documentation

The following functions are currently implemented:

• head(arr): takes a given array and returns the first element
• tail(arr): takes a given array and returns the everything except the first element
• middle(fullArray): takes a given array and returns the element(s) in the middle
• countLetters(sentence): takes a given sentence and returns an object with a count of how many times each letter appeared
• countOnly(allItems, itemsToCount): takes an array of items, and an item to count and returns the number of times that item appears
• findKeyByValue(object, value): takes an object and a value, and returns the key at which that value is found
• findKey(object, callback): takes an object and a callback, scans the object, and returns the first key for which the callback returns a truthy value. If no key is found it returns undefined
• flatten(tallArray): takes an array of elements that include nested arrays, and returns a flat array of all enclosed elements

• takeUntil(array, callback): takes a given array and a callback as arguments and returns an array that includes the elements of the input array until the callback returns a truthy value, then it will stop
• without(sourceArray, itemsToRemove): takes an array and a set of unwanted elements to remove from that array, and returns a new array of only the wanted items
• eqArrays(arr1, arr2): takes two arrays and compares if they are equal, returns true if so and false if not
• eqObjects(object1, object2) takes two objects and compares if they are equal, returns true if so and false if not
