Converting enums to array of values (Putting all JSON values in an array)

Question

I use this method Enums in JavaScript? to create enums in our code..

So

var types = {   "WHITE" : 0,   "BLACK" : 1 } 

Now the issue is when I want create validations anywhere, I have to do this;

model.validate("typesColumn", [ types.WHITE, types.BLACK ]); 

Now is there a way I can just simple convert the values in types to an array so that I don't have to list all of the values of the enum?

model.validate("typesColumn", types.ValuesInArray]); 

EDIT: I created a very simple enum library to generate simple enums npm --save-dev install simple-enum (https://www.npmjs.com/package/simple-enum)

Answer 1

Simple solution (ES6)

You can use Object.values like this:

var valueArray = Object.values(types);

Answer 2

I would convert the map into an array and store it as types.all. You can create a method that does it automatically:

function makeEnum(enumObject){    var all = [];    for(var key in enumObject){       all.push(enumObject[key]);    }    enumObject.all = all; }
