Declare and use an enum in Node.js with Geddy

My preferred Enum package for node is https://www.npmjs.com/package/enum.

Here is a basic usage (copied from documentation):

// use it as module
var Enum = require('enum');

// or extend node.js with this new type
require('enum').// define an enum with own values

var myEnum = new Enum({'A': 1, 'B': 2, 'C': 4});

And then you can use for example a simple switch case statement like:

let typeId = 2;

switch (typeId) {
    case myEnum.A.value:
        //Do something related to A.
    break;
    case myEnum.B.value:
        //Do something related to B.
    break;
    case myEnum.C.value:
        //Do something related to C.
    break;
    default:
       //Throw error
    break;
}

You should use objects like;

const kindOf = {
    TYPE1: 'type1',
    TYPE2: 'type2',
    TYPE3: 'type3'
}

let object_type = kindOf.TYPE1;

Remember that Node is just javascript, and javascript does not (to the best of my knowledge) have enums. You can however fake it, which is discussed here: Enums in JavaScript?
