Destructuring with default intermediate values

I’d like to use default intermediate values in destructuring like:

const { (form = {}): data = {} } = {};

Any way to assign a default {} to form? Couldn’t find, seems impossible.

>Solution :

You need to take the right syntax for destructuring nested objects and a default value at the end.

const getData = object => {
    const { form: { data = {} } = {} } = object;
    return data;;
};

console.log(getData({}));
console.log(getData({ form: {} }));
console.log(getData({ form: { data: { foo: 42 } }}));
