Create an object with only some attributes from another object in javascript

Question

With the new ES6 syntax, it's easy to only select some keys of an object and assign their values to variables with the same name. It goes like

let foo = {a: 2, b: 1, c:6};
{a, b} = foo;

which is equivalent to

let a = foo.a, b = foo.b;

It's also easier to create objects from variables, like

let bar = {a, b}

which is equivalent to

x = {a: a, b: b}

Now is there a shorthand to get bar from foo directly? (with bar = {a: foo.a, b: foo.b})
