Chapter 3
Advanced Smart Contracts with Solidity
Section 6
Utilizing Solidity Mappings and Structs
We've already covered a lot of concepts in advanced smart contract programming. This lesson will complete any knowledge about Solidity syntax and available commands which haven't yet been covered. - Understand returning output from a smart contract - Use assertions in Solidity to handle errors and exceptions - Emit events and how they can be listened for by a DApp frontend
