How to optimize the search for the desired phrase in json objects?

Question

Node.js

Now it will be absurd, and you will write why I need this, BUT there is a web socket through which an array with data arrives every 2 seconds

[
  {
    "id": 345,
    "descripton": "test follow maybe test test"
  },
  // ... 740 length
]

And my list of phrases, for 1 million lines

[
  "test test test test test",
  "test test test test test",
  "test test test test test",
  "test test test test test",
  "test test test test test",
  "test test test test test"
  // ... 1mln length

When new websocket data arrives, I check it

for (object of wsData) {
  for (myPhrase of myPhrasesList) {
    // Если есть совпадение, вызываю функцию отправки сообщения в тг и отдельный запрос на сайт
  }
}

So, with a load of 1 million lines, sending a message to tg and a separate request to the site takes a lot of time than with a load of 10k, with 10k lines, everything works perfectly.
upd
what I meant, the search itself is fast and the function is also called in a matter of seconds, but the execution of the function is slow, and can take up to 40 seconds

. So, how to optimize all this crap, and so that everything works smartly and nicely? At the same time, so that everything does not fall off under load, because as I understand (well, my guess) the data comes every 2 seconds, and the load grows more and more and this is bad because the past data does not have time to be checked when new ones arrive. Are there solutions?

Answer 1

// Это должно быть вне обработчика закэшировано
const myPhrasesList = new Set([
  "test test test test test",
  "test test test test test",
  "test test test test test",
  "test test test test test",
  "test test test test test",
  "test test test test test"
  // ... 1mln length
]);

for (object of wsData) {
    if (!myPhrasesList.has(object.description)) {
       continue;
    }

    this.notification(object, object.description).then()
}
