javascript - Enum using empty objects -

we can create "enums" in javascript follows:

var myenum = {     a: 0,     b: 1, } 

can use empty objects instead of numbers follows?

var myenum = {     a: {},     b: {}, } 

what's difference , should used? there isn't specific use case.

i changed answer after edited because noticed trying.

yes can use objects enum value without problem. when define {} in object, creates , empty object unique reference.

{} != {} won't equal because 2 different objects same doesn't mean same object. 2 red balls have, these balls same ball? no.

but instance.type == myenum.objectenum1 true. because both instance , myenum object shares same reference object.

var myenum = {    a: 1,    b: 2,    c: 3,    objectenum1: {},    objectenum2: {}  }    var obj1 = {  	type: myenum.b  }    var obj2 = {  	type: myenum.c  }    var obj3 = {  	type: myenum.objectenum1  }      console.log(obj1.type == myenum.b); //should true  console.log(obj2.type == myenum.a); //should false  console.log(obj2.type == myenum.c); //should true      console.log(obj3.type == myenum.objectenum1); //should true  console.log(obj3.type == myenum.objectenum2); //should false
