How to use an object as an argument in JavaScript subclasses?

For example, if I have something like this:

class X{
    constructor({one, two}){
        this.one = one 
        this.two = two
    }
}

class Y extends X{
    constructor(props, three){
        super(props)
        this.three = three
    }
}

And I want to create an object with:

console.log(new Y({one: 1, two: 2, three: 3}))

Is it possible? I tried other ways like:

console.log(new Y({one: 1, two: 2}, 3))
console.log(new Y({one: 1, two: 2}, {three: 3}))

but they are uncomfortable.

You can do that...yes
just use the destructuring assignment

 class X { constructor({one, two}) { this.one = one this.two = two } displaying() { console.log(this) } } class Y extends X { constructor({three, ...OneTwo}) { super(OneTwo) this.three = three } } let zz = new Y({one: 1, two: 2, three: 3}) zz.displaying()
