Documentation

The following functions are currently implemented:

• head(arr): function to retrieve the first element from the array
• tail(arr): function to retrieve every element except the head (first element) of the array
• middle(arr): function return an array with only the middle element(s) of the provided array
• countLetters(str): function should take in a sentence (as a string) and then return a count of each of the letters in that sentence
• countOnly(allItems, itemsToCount): function should take in a collection of items and return counts for a specific subset of those items. countOnly will be given an array and an object. It will return an object containing counts of everything that the input object listed
• findKey(obj, cb):function scan the object and return the first key for which the callback returns a truthy value
• findKeyByValue(obj, valueOfObj): function search for a key on an object where its value matches a given value
• letterPositions(sentence): function return all the indices (zero-based positions) in the string where each character is found
• map(arr, cb): function will return a new array based on the results of the callback function. Manually rewrite .map()
• takeUntil(arr, cb): function will return a slice of the array with elements taken from the beginning
• without(source, itemsToRemove): function to filter our data by removing some unwanted items from given array
• eqArrays(arr1, arr2): function that can compare two arrays for a perfect match
• eqObjects(obj1, obj2): function takes in two objects and returns true or false, based on a perfect match
