I was trying to make a bad words filter with my bot in discord.js v13 and node.js v16. I wrote a simple code but It's not working correctly.

My code:

const args = message.content.split(/  /);
if ((message.guild.id = 'GUILD_ID')) {
  const bad = ['word1', 'word2'];
  if (bad.includes(args[0].join(' '))) {
    message.delete();
  } else {
    return;
  }
}

When I send a 'word1' message, It works correctly and deletes the message. but when I send for example: "Hello word1", It does not work.

What does It need to do?

1. Delete the message if it includes a bad word.

Note: I am not getting any errors!

It's because you check if the array contains the string "Hello word1".

You can use Array#some() with a callback function to check if the string contains any of those words in the array:

function containsBadWords(str) {
  const badWords = ['word1', 'word2']

  if (badWords.some(word => str.toLowerCase().includes(word))) 
    return 'String contains bad words'
  else 
    return 'No bad words found'
}

console.log(containsBadWords('word1'))
console.log(containsBadWords('Some other text that includes word2 here'))
console.log(containsBadWords('No bad words here'))

// make sure you don't use single '=' here!
if (message.guild.id === 'GUILD_ID') {
  const bad = ['word1', 'word2']
  if (bad.some(word => message.content.includes(word)))
    message.delete()
  else
    return
}

array includes will not return true for your Hello world1 string. In your case you want to find if array includes that value by substring. This is not the way array.includes method works. Check out this answer In javascript, how do you search an array for a substring match
