Where Value Objects represent pieces of immutable data without an identity, entities represent identifiable elements within our systems. Entities generally have a lifecycle. They can be created, oftentimes deleted and are expected to be mutated during their lifespan.

In an ideal world non-technical colleagues would be able to read our code and quickly recognise the concepts, rules and processes that make up the business. We might never reach such an ideal but I’d argue we should strive for it nonetheless. Value Objects offer one way of getting us closer to that ideal situation.
