Getting first array element within object using destructuring [duplicate]

Question

x = { foo: [ { foo: 'foo' } ], bar: [ { bar: 'bar' } ] };

Is it possible to get {foo: 'foo'} and { bar: 'bar' } in one line?

Something like this

({ foo, bar } = x);

would produce [{"foo":"foo"}] [{"bar":"bar"}] which are two arrays and not objects. Of course these arrays can be further destructured, but I'm interested in a one line implementation

const { foo: [foo], bar: [bar] } = x

You can use array destruction to get the first element:

const { foo: [ firstFoo ], bar: [firstBar ]} = x;
