The following functions are currently implemented:
assertEqual function
: to provide test code to let us determine if we have failed assertions.head function
: to retrieve the first element from the array.tail function
: to retrieve every element except the head (first element) of the array.eqArrays function
: to compare two arrays for a perfect match.assertArraysEqual function
: asserting that two arrays are equal.without function
: to remove some unwanted items.middle function
: to retrieve the middle element from the array.countOnly function
: to take in a collection of items and return counts for a specific subset of those items.countLetters function
: to take in a sentence (as a string) and then return a count of each of the letters in that sentence.letterPositions function
: to return the index in the string where each character is found.findKeyByValue function
: to search for a key on an object where its value matches a given value.eqObjects function
: take in two objects and returns true or false, based on a perfect match..assertObjectsEqual function
: to help us easily test functions that return objects.map function
: to return a new array based on the results of the callback function.takeUntil function
: to keep collecting items from a provided array until the callback provided returns a truthy value.findKey function
