Javascript Tutorial - Enum Types

In reality Javascript does not support enumerated types, but what you can do is define a global constant object that looks and behaves like an Enum.

We look at how you can use this method to define an 'enum' that stores the values for directions that a player might be moving towards in a game.

There are many ways to do this so if you have any better ideas I'd love to hear your feedback in the comments!

generally when i define my enums i always use Object.freeze on them and use numbers as values just to make sure they really act like enums

Thanks, man. I like using Enums b/c it can translate inputs to a word format, rather than using numbers, so I was disappointed to find that JavaScript doesn't have them. I'll keep this in mind for the future. 👍

Enums seem like such a pointless structure in JS, you essentially created a hash map via an object literal... Enums are a fluffy idea that is totally pointless in languages like JS and Python.

Except the values of that Object should be numbers hence the name ENUMERATION.
