How do I check if specific words contain in JS

I have a problem checking if the the word "product" is there.
add a header called "newProduct" with a value of "yes".
Right now my problem is that if the collectionName has a word of "e23product32", it doesn't add the header

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const productTags = [
  "product"
];
const collectionName = 'e23product32';
const headers = {
  ...(productTags.some((tag) => tag.includes(collectionName)) && {
    "newProduct": "yes",
  }),
};
console.log(headers);

<!-- end snippet -->

You've got your check back-to-front... "product" does not contain (include) "e23product32" but "e23product32" does contain "product"

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const productTags = ["product"];
const collectionName = "e23product32";
const headers = {
  ...(productTags.some((tag) =>
    collectionName.toLowerCase().includes(tag.toLowerCase())
  ) && {
    newProduct: "yes",
  }),
};
console.log(headers);
