Detecting a specific word in a message in discord.js-CodePudding

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.

CodePudding user response：

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.

CodePudding user response：

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)
})
