Functions are a core feature of any programming language. They allow us to simplify our codebase by writing code once inside a function. And then calling that function whenever we need it.

In Solidity, functions can read, write, change, and store data in the smart contract. You can pass arguments (parameters) into a function. And that function can return values if you want it to.

Events vs Functions in Solidity

Events vs Functions in Solidity. In Solidity, functions can read, write, change, and store data in the smart contract. You could fire this event when you transfer an ERC721 token from one user to another in your smart contract. Calling events are just like calling a function with one big difference. Events use the emit keyword. This let's developers know an event is being called and not a function.
