use filter to return property values in an object

Question

Trying to make a function that uses filter but not a for or while loop or foreach function, that will loop through an array of objects only to return their property values.

Answer 1

In addition, I am using ES6 Destructure with filter and compare two object array. And finally map specific fields those i need actually.

Initialization

const bumperDealRules =[]; // Array object
const cartItems =[]; // Array object

Final code

const bumperDealsSelected = bumperDealRules.filter(
            ({ item_display_id: item_display_id, purchasequantity: purchasequantity }) 
            => cartItems.some(({ id: id, action_from: action_from, order_qty:  order_qty }) 
            => id === item_display_id && purchasequantity <= order_qty &&  action_from == 'bumper_deal' ) 
        ).map(function(obj) {
            return { 
                bumper_deal_company_name_id: obj.bumper_deal_company_name_id, 
                from_amount: obj.from_amount,
                to_amount: obj.to_amount,
                discount: obj.discount,
                highest_limit: obj.highest_limit
             };
          });
