design patterns - Correct JavaScript 6 type to use for c# equivalent of struct -

i'm still getting used working javascript after many years of working in c#.

i have object i'd instantiate. object has same 7 fields in it. it's used pass set of 7 numbers around various functions.

var myobj = {      4: 0,     6: 0,     8: 0,     10: 0,     12: 0,     20: 0,     100: 0 }; 

in emcascript 6, classes have been defined, i've found on web, classes seem used defining functions on class, similar prototype of emcascript 5 function, , not defining fields.

what's proper way this?

my thinking right it's like:

var myobj = function () {     this[4] = 0;     this[6] = 0;     this[8] = 0;     this[10] = 0;     this[12] = 0;     this[20] = 0;     this[100] = 0; };  var obj = new myobj(); 

i don't believe matter of opinion. in languages, there right way this.

the way in c# is

struct myobj {     public int fours { get; set; }     public int sixes { get; set; }     public int eights { get; set; }     public int tens { get; set; }     public int twelves { get; set; }     public int twenties { get; set; }     public int hundreds { get; set; } } 

to create object in javascript similar struct specified , able reuse object, try creating function returns template of object:

function createmyobj() {      return {          "4": 0,         "6": 0,         "8": 0,         "10": 0,         "12": 0,         "20": 0,         "100": 0     };  } 

there many different creational patterns in javascript, depends on needs. need object hierarchy? use prototype pattern. need object creation takes in default paramaters, sort of constructor? use implementation similar 1 specified above modify accept defaultvalues object contains or of properties need specifiy.
