javascript - Is it possible to sort a ES6 map object?

Question

Is it possible to sort the entries of a es6 map object?

var map = new Map();
map.set('2-1', foo);
map.set('0-1', bar);

results in:

map.entries = {
    0: {"2-1", foo },
    1: {"0-1", bar }
}

Is it possible to sort the entries based on their keys?

map.entries = {
    0: {"0-1", bar },
    1: {"2-1", foo }
}

According MDN documentation:

A Map object iterates its elements in insertion order.

You could do it this way:

var map = new Map();
map.set('2-1', "foo");
map.set('0-1', "bar");
map.set('3-1', "baz");

var mapAsc = new Map([...map.entries()].sort());

console.log(mapAsc)
