• without(arr1, arr2): Returns a new array which equals the element of the first - the second.
• takeUntil(arr, val): Iterates through each item of array and pushes them to a new array until it element of the array matches the value.
• assertEqual(actual, expected): Checks strickt equality between two values and console logs the result.
• eqArrays(arr1, arr2): Returns true or false if the arrays match.
• assertArraysEqual(arr1, arr2): Uses eqArrays to log if the arrays match.
• eqObjects(obj1, obj2): Returns true or false if the objects match.
• assertObjectsEqual(arr): Uses eqObjects to log if the objects match.
• findKey(obj, val): Scans the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
