NodeJS how to add objects to a set and iterate?

Question

This should be really straightforward but i haven't got it to work.

var Set = require("collections/set");

function User() {
    this.name = 'something';
}

var clients = new Set();

var a = new User();
var b = new User();
clients.add(a);
clients.add(b);

var arr = clients.toArray();
for (var user in arr) {
    console.log(user.name+' iterated');
}

Why am i getting:

undefined iterated
undefined iterated

What i want to get is:

something iterated
something iterated

Solution

var Set = require("collections/set");

function User() {
    this.name = 'something';
}


var clients = new Set();

var a = new User();
var b = new User();
clients.add(a);
clients.add(b);


var arr = clients.toArray();
for (var i=0;i<arr.length;i++) {
    console.log(arr[i].name+" iterated");
}
//something iterated
//something iterated

Doesn't look like it's smart enough, i am getting SyntaxError: Unexpected identifier - On the "of" part.

Then do what sumeet has posted, that will work if you can get an actual array.

I do not need to require Set in NodeJS version 12. It was throwing an error when i did. It is available by default
