Documentation

The following functions are currently implemented:

• countLetters(string): takes in a string and returns the number of times each letter in that string appears.
• countOnly(array, object): given an array and an object. It will return an object containing counts of everything that the input object listed.
• eqArray(arr1, arr2): takes in two arrays, returns true if they are the same. False otherwise.
• eqObject(obj1, obj2): takes in two objects, returns true if they are the same. False otherwise.
• findKey(object, function): takes in an object and a function. Return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• findKeyByValue(object, string): Takes in an object and a value. Returns the first key which contains the given value. If no key with that given value is found, then returns undefined.
• flatten(array): Takes in a nested array and returns a new array single-level array. (does not handle multi-level arrays)
• head(array): takes in an array, returns the "head" of an array.
• letterPositions(string): takes in a string and return all the indices (zero-based positions) in the string where each character is found.
• map(array, function): takes in an array and a function. Returns new array based off of the results of the function.
• middle(array): takes an array and returns the middle(s) elements(s).
• tail(array): takes in an array, returns the "tail" of an array.
• takeUntil(array, function): Takes in an array and function. Return a new array starting from the begining of the original array until function returns truthy.
• Without(arr1, arr2): takes one array and other array of elements to remove. Returns new array.
