Question

Recently I am learning to make javascript class, I saw other people make class like this

var item = {
     'a':{'b':1000,'c':2000,'d':3000} , //how to make a variable become an array?
     myfunction : function(){
         console.log(item.a.b); //and output item.a[1]?
     }
 };
 item.myfunction();

But is it possible to make variable a an array? and output a variable item.a[1] like that?I tried

var a=new Array('1000','2000','3000')
but error, I need a correct syntax.

Answer 1

var item = {
    'a': [1000, 2000, 3000],
    myfunction: function () {
        console.log(this.a[1]);
    }
};

But that’s not a class, and there is no “variable a”.
