Filter an array of objects in Angular2 based on properties that are not included in the specified values

I'm encountering some difficulties while filtering an array of objects based on a specific set of values:

Here is the array that needs to be filtered:

const items: Product[] = ... values

Next, I have created an array containing the products that I wish to select:

const sel: Product[] = ... values

The property that I need to use for applying the filter is idProduct. How can I achieve this?

I am looking for something along the lines of:

const query = items.filter(item => sel.map(s => s.idProduct).includes(item.idProduct))

Any ideas on how to make this work?

Appreciate your assistance.

Answer №1

If you want to locate products in sel that share the same product id, you can utilize the some method.

items.filter(item => sel.some(selection => selection.idProduct == item.idProduct));

Answer №2

After analyzing the previous responses, I have come up with a solution using the Array.prototype.includes() method:

let result = items.filter(item => selection.map(sel => sel.productId).includes(item.productId));
