ES6 Object Literal Property Value Shorthand

Question

Using the new shorthand feature in ES6 for object literals, is it possible to use obj.id and have it parse as id: obj.id? Wondering if I've missed something in the new spec...

create(obj) {
    this.connection.send({
        obj.id
    });
    this.add(obj);
},

Answer 1

No, there is not. Shorthands do only work for variables, so you should use {id: obj.id}.

Answer 2

Although Bergi response is correct, you could create a variable for id:

create(obj) {
    const { id } = obj;
    this.connection.send({ id });
    this.add(obj);
},

For the specific case you mention it's a overload, but on other cases it might be useful.
