为 GTM 自定义 javascript 变量数组添加过滤器

Question

We have a ecommerce system that pushes through a datalayer. Unfortunately, the datalayer includes the 'building blocks' of our products. Resulting in tags that register more information than I would like. I would like to exclude these 'building blocks' through a custom javascript variable. See an example of the datalayer below.

    checkout: {
      actionField: {step: 1},
      currencyCode: 'EUR',
      products: [
        {
          name: 'product name',
          id: '40291',
          price: '149,00',
          category: 'Transportation/Other',
          quantity: 2
        },
        {
          name: 'building block 1',
          id: '20231',
          price: '0,00',
          category: 'Transportation/Other',
          quantity: 2
        },
        {
          name: 'building block 2',
          id: '12302',
          price: '0,00',
          category: 'Transportation/Other',
          quantity: 2

I've made a CJS variables that makes the products.id, .name, .price and.quantity an array (see below), but I am unable to figure out how to add a filter() that excludes from the array the values where corresponding product.name = "building block 1" && "building block 2".

  var products = {{dlv - product}};
  return products.reduce(function(arr, prod) { return arr.concat(prod.id); }, []);

Would anybody be able to help me out with this part of the function? Alternatively, I was thinking I might be able to achieve the same with a conditional if() statement.

Thanks in advance!

I'm not sure how GTM works, but if you want to filter an array with JS you could use something like this:

checkout.products.filter(product => !product.name.includes('building block'))

Let me know if this helps or I'm missing something.
