Documentation

The following functions are currently implemented:

• head(array): returns the first item in an array
• middle(array): returns middle item in an array of odd length, and the middle two items in an array of even length
• tail(array): returns the last item in an array
• assertArraysEqual(array1, array2): compares two arrays for strict equality and logs output msg to console
• eqArrays(array1, array2): returns boolean when comparing two arrays
• assertObjectsEqual(object1, object2): compares two objects for strict equality and logs output msg to console
• eqObjects(object1, object2): returns boolean when comparing two objects
• map(array, callback): applys a callback function on an array, returns a new array
• flatten(array): flattens an array of arrays to one level deep. returns a new array
• letterPositions(string): returns an object where the keys represent each letter of the string, and values are arrays representing the index of where those letters are located in the string
• findKeyByValue(obj, val): searches an object keys for a specific value, then returns that key
• findKey(object, callback): applys a callback function on every key of an object, and if it returns true, returns that key
• countOnly(allItems, itemsToCount): iterates through an array (allItems) and counts the number of times an item exists in that array (itemsToCount) and returns an object of with the results
• countLetters(string): interates through a string, and retuns an object dispalying how many times each letter was found
• takeUntil(array, callback): iterates through an array and pushes each element to a new array until the callback function returns a true. returns the new array
• without(source, itemsToRemove): iterates through an array and pushes each element that does not meet the specified criteria. returns new array
