Detecting a specific word in a message in discord.js

Question

I tried the 2 solutions posted here to detect a specific words and they do work:

Solution 1

const badMessages = ["bad", "worst"];
badMessages.forEach((word) => {
if (message.content.includes(word)) {
message.reply("Detected.");
}
})

Solution 2

const badMessages = ["bad", "worst"];
for(var i=0; i<badMessages.length; i++) {
if (message.content.includes(badMessages[i])) {
message.reply("Detected.");
}
}

However, the condition triggers even when the word in the array for example bad is mixed with other words like "badge". How do I detect a specific word by itself which should trigger for the exact "bad" word only and not trigger when it is mixed with other words like badge.

Answer 1

You can try to wrap all bad words with spaces, so it will only search for those specific words separated by spaces?

Better solution would be to use a regular expression like what has been suggested here.

Answer 2

you can use the regular expression \b(bad|wrong)\b

const messages = [
    'bad bads man wrong',
    'bads man wrong',
    'abad man wrong',
    'abad man wrongs',
    'abad man awrong',
    'bad man',
    'wrong man',
    'badge text'
]
const badMessages = ["bad","wrong"];

messages.forEach(x => {
  const regex = RegExp(`(\\b)(${badMessages.join('|')})(\\b)`, 'g')
  //const regex = RegExp(`(\\b)(${badMessages.join('|')})(\\b)`, 'gi') for case insensitive 
  const isMatch = regex.test(x)
  console.log(isMatch)
})
