درباره این درس
A value object is an object whose equality is determined by its data (or value) rather than any particular identity. To illustrate this, imagine three five dollar bills resting on a table. Does one bill have a unique identity compared to the other two? From our perspective, no. Five dollars is five dollars regardless of which bill you choose. However, compare this with two human beings who have the same first and last name. Are they identical, or does each person have a unique identity? Of course in this case, the latter is the correct answer.
