Enums

Enums are one of the most popular concepts within programming. They are not very difficult to explain or understand, and they are widely used when programming systems that have a complexity above what we can consider as something basic.

In general, the definition of an enum is that it is a special type of data that represents a fixed set of values. That is, we have a list of possible and unique values for a type of variable. A classic example of this is the days of the week (Monday, Tuesday…) but why use an enum instead of constants? Enums provide several advantages over constants: they are type-safe, ensuring that only valid values are used; they group related constants into a single type, making the code more organized and readable; and they can include additional properties or methods, adding more functionality compared to plain constants.

We know that the days, for example, do not change, and if we use them within a program, we could manage them in a fixed...
