The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - What Are Enums in Solidity

The video tutorial explains enums in programming, focusing on their use in Solidity. Enums restrict variables to predefined values, reducing bugs. The tutorial demonstrates setting up enums, initializing them, and creating functions to manipulate and retrieve enum values. A practical example using French fries sizes illustrates these concepts, showing how to set default values and change them through functions.
