• assertObjectsEqual(actual, expected): Returns if the actual object is equal or inequal to the expected object;
• eqObjects(object1, object2): Returns if given objects are equal or inequal
• findKey(object, callback): Determines whethere a key that passes a callback function is present in a given object, and returns the key if so;
