Thoughts:

1. use .filter to filter the array based on a function, docs
2. use .find to check whether each item has your desired property, in this case, a tag with the name sales, docs

const array = [
  {
    tags: [
      {
        name: "Hit",
        slug: "hit"
      },
      {
        name: "Sale",
        slug: "sale"
      }
    ],
    price: 6000,
    stock: 10,
    name: "Name Product",
    description: "Test",
    slug: "name-product"
  },
  {
    tags: [
      {
        name: "Sale",
        slug: "sale"
      }
    ],
    price: 6000,
    stock: 10,
    name: "Name Product 2",
    description: "Test 2",
    slug: "name-product-2"
  },
  {
    tags: [
      {
        name: "NotSale",
        slug: "notsale"
      }
    ],
    price: 6000,
    stock: 10,
    name: "Name Product 2",
    description: "Test 2",
    slug: "name-product-2"
  }
];

const filteredArray = array.filter((t) => {
  return t.tags && t.tags.find((tag) => tag.name.toLowerCase() === "sale");
});

console.log(filteredArray);
