How do I check for a word in a message, in discord js?

Question

I'm trying to make a simple discord bot. How can I make it so it checks for a word inside a message? For example if somebody says "i love bananas" and the trigger word is banana, the bot responds with "same". All I could figure out is how to make it reply to a specific message (like only "banana"), how do I make something like the example I made?

string has "indexOf" which returns the index if exist and -1 if not — Jafar Jabr, Jan 10 '22 at 20:51

Please add the code where you read and process the discord message to your question. — kevintechie, Jan 10 '22 at 21:02

discord.js v13.5.1

const client = new Client({
  intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES],
});

const triggerWords = ['banana', 'fire', 'white'];

client.on('messageCreate', (message) => {
  if (message.author.bot) return false;

  triggerWords.forEach((word) => {
    if (message.content.includes(word)) {
      message.reply(message.content);
    }
  });
});
