isEmptyObject(obj)

Used to determine if an object is an empty object (an object with no enumerable properties) such as {}.

var isEmptyObject = require("can-util/js/is-empty-object/is-empty-object");

console.log(isEmptyObject({})); // -> true

console.log(isEmptyObject({ a: 1 })); // -> false

var obj = {};
Object.defineProperty(obj, "foo", {
    enumerable: false,
    value: "bar"
});
console.log(isEmptyObject(obj)); // -> true
