Make enums available in JavaScript

ModelWithEnum.cs

// Drop ModelWithEnum.ThingTypeDictionary into a ViewModel that gets serialized to JSON
// for handy, scalable use of enums in JavaScript. For example, you can change
//
//
// if (m.ThingTypeId === 3)
//
// to
//
// if (m.ThingTypeId === model.ThingTypeDictionary.Spaceship)

namespace App.Models {
    
    public class ModelWithEnum {
        
        public TypeOfThing ThingTypeId { get; set; }
        
        public static Dictionary<string, int> ThingTypeDictionary = Enum.GetValues(typeof(TypeOfThing)).Cast<int>().ToDictionary(t => Enum.GetName(typeof(TypeOfThing), t), t => t);
        
    }

    public enum TypeOfThing {
        Foo = 1,
        Bar = 2,
        Spaceship = 3,
        Submarine = 4
    }
