var list = [...Array(1000).keys()].map((index) => {return {id: index, name: `PRODUCT_${index}`}});
var newItems = [{id: 50, name: 'CUST_50'}, {id: 412, name: 'CUST_412'}];
var newItemIds = newItems.map((item) => item.id);
Tests:

  • includes

     
    list.filter((item) => {
      return !newItemIds.includes(item.id);
    });

  • indexOf

     
    list.filter((item) => {
      return newItemIds.indexOf(item.id) === -1; 
    });
