• 'tail(array)' : Takes in array and returns all items in array except array0;
• 'middle(array)': Takes in array and returns with middle index of array if oddly numbered, and two most middle if evenly numbered.
• 'map(array, callback)': Takes in an array and returns a new array based on the results of the callback fucntion.
• 'letterPositions(string)': Takes in a string and returns all the indices in the string where each character is found.
• 'head(array)': Takes in a array and returns the first index of the array.

• 'eqArrays(array1, array2)': Takes in two arrays, returns true if both arrays are equal (same values at same index), returns false otherwise.
• 'countOnly(allItems, itemsToCount)': Takes in an array of objects, returns an object containing counts of everything the input object listed.
• 'countLetters(string)': Takes in a string, returns a object showing all the letters in the string and how many times it occurs.
• 'assertObjectsEqual(actual, expected)': Assertion test for the eqObjects function.
• 'assertEqual(actual, expected)': Basic assertion test if actual === expected inputs.
• 'assertArraysEqual(array1, array2)': Assertion test for eqArrays function.
