• middle(array): middle accepts an array and returns the middle elements of the array. If the array has an odd number of elements it will return only one element, if it has an even number of elements it will return the two middle elemnts
• assertEqual(actual, expected): will log "🤑🤑🤑Assertion Passed:" if the actual === expected, and "😡😡😡Assertion Failed:" if the actual !== expected
• assertArraysEqual(array1, array2): will log "🤑🤑🤑Assertion Passed:" if array1 === array2, and "😡😡😡Assertion Failed:" if the array1 !== array2
• assertObjectsEqual(object1, object2): will log "🤑🤑🤑Assertion Passed:" if object1 === object2, and "😡😡😡Assertion Failed:" if the object1 !== object2
• countLetters(string): will return an object with the number of occurences of a specific character
• countOnly(allItems, itemsToCount): will return an object with the number of occurences of the characters specified in the items to count object
• eqArrays(array1, array2): checks if array1 === array2
• eqObjects(object1, object2): checks if object1 === object2
• findKey(obj, callback): returns the key that meets the criteria specified by the callback function
• findKeyByValue(obj, value): returns the key that contains the specified value returns undefined if key does not exist
• flatten(array) : returns a the given array one level flatter
• letterPositions(string) : returns an object with the location of each letter specified in an array
• map(array, callback): returns a new array of elements that were modified by the callback function
• takeUntil(array, callback) : returns a slice of the given array until the specified callback criteria is met
