Documentation

The following functions are currently implemented:

• head() - returns the first item in the array.

• tail() - returns everything except the firs item (head) of the array.

• assertEqual() - will take in two primitive types and will console.log a statement stating whether they match.

• eqArrays() - takes in two arrays and returns true or false, based on a perfect match of the contents of the array.

• assertArraysEqual() - takes in two arrays and will console.log a satement stating whether they are equal.

• without() - will return a subset of a given array, removing unwanted elements.

• middle() - takes an array and will take in an array and return the middle-most element(s) of given array. For an input with an even number of elements, this function will return 2 elements. For an input with an odd number of elements, this function will return 1 element.

• countOnly() - this function takes an object of items and returns a count for a specific subset of those items. It will only count the specified items.

• countLetters() - takes in a string and returns the count of letters in the string.

• letterPositions() - takes in a string and returns the index(es) of where the letters are used in the string.

• findKeyByValue() - given a value, this function will return the key of where the value is located.

• eqObjects() - will test whether the keys and values of the objects are identical. Returns true or false.

• assertObjectsEqual() - will take in two objects and console.log a statement stating whether they are equal.

• takeUntil() - takes in an array and returns the contents of the array until a specified value in the array.

• findKey() - takes in an object, and a value. Returns the key in which the value is located. If no key is found, it will return undefined.
