🧟 Level 3: The Creation Engine — Powering Up the Factory (Solidity Quest)

A Solidity tutorial adds a private `_createZombie` function to `ZombieFactory` that builds a `Zombie` struct from a name and DNA value.

The function then stores the new struct in the `zombies` array using `push()`, showing how contracts manage on-chain state.

It also explains that functions are public by default in Solidity, so private visibility is used to block direct outside calls to the factory logic.

The example highlights two core ideas in Ethereum development: contract execution and access control.
