How to unpack nested data into a function?

Question

I want to pull the income property from an object into a function var:

    let obj1 = {
        x: {
            income: 200,
            sex: 'male'
        },
        y: 'name1'
    };

    function informUserData({
     //what to put here ?
    }){
        return income;
    }
    console.log(informUserData(obj1));// it should be 200

I tried this:

function informUserData({
     x{
         income
     }
    }){
        return income;
    }
    console.log(informUserData(obj1));

Then, I tried this, just to check how to unpack a no-nested property value.

    let obj1 = {
        x: {
            income: 200,
            sex: 'male'
        },
        y: 'name1'
    };

    function informUserData({
     y
    }){
        return y
    }
    console.log(informUserData(obj1)); // name1

Answer 1

I got that the problem was a syntax problem Instead of property property I needed property : property. So:

    let obj1 = {
        x: {
            income: 200,
            sex: 'male'
        },
        y: 'name1'
    };

    function informUserData({
     x: {income}
    }){
        return income
    }
    console.log(informUserData(obj1))
