Sometimes when working with objects we wish to extract values in the nested objects contained within these objects. In this blog post we will go over how to do that.

Example

Suppose we have the following object:

const item = {
    id: 345,
    itemId: 'ABC123493549KKJ9',
    name: "Jay's Peanut Butter",
    company: 'J&P Products',
    price: 6.99,
    quantity: 45,
    locations: {
        locationId: 673,
        quantity: 21        
    }
}

Suppose we want the value of locationId. In order to extract it from the nested object, we do the following:

const {locations: {locationId}} = item;
console.log(locationId); //673
