I saw the post on how to add a cooldown for a twitch bot (cooldown for twitch bot) and the response given by @Ma3x is just what I needed (pasting it here for reference):

// the time of the last help message
let lastHelpTime = 0

client.on('message', (channel, tags, message, self) => {
    const send = message === "!help"

    if (!send ) return;

    // get the current time
    const timeNow = new Date().getTime()
    // check if at least 1 minute has elapsed since the last help message
    if (timeNow - lastHelpTime > 60 * 1000) {
        // update the last help message time
        lastHelpTime = timeNow
        // post the help message in chat
        client.say(channel, `This is the help message`)
    }

    console.log(`${tags['display-name']}: ${message}`);
});

However, it detects the exact word only. How do I make it detect any variation of the word "!help" like "!HELP", "!HeLp" or when it's part of the message like "!help bot chat"?

Thank you!

Use the JavaScript .toLowerCase() function to convert everything in the message to lower-case and .includes() to check for the matching string in the message when comparing the message to your desired text (read more toLowerCase and includes):

// the time of the last help message
let lastHelpTime = 0

client.on('message', (channel, tags, message, self) => {
    const send = message.toLowerCase().includes("!help")

    if (!send ) return;

    // get the current time
    const timeNow = new Date().getTime()
    // check if at least 1 minute has elapsed since the last help message
    if (timeNow - lastHelpTime > 60 * 1000) {
        // update the last help message time
        lastHelpTime = timeNow
        // post the help message in chat
        client.say(channel, `This is the help message`)
    }

    console.log(`${tags['display-name']}: ${message}`);
});

Example:

console.log("!HELP".toLowerCase().includes("!help"))
console.log("!HeLp".toLowerCase().includes("!help"))
console.log("!help".toLowerCase().includes("!help"))
console.log("!hElp mE Bot".toLowerCase().includes("!help"))

Note: This only checks to see if "!help" is part of the message, and not the -first- part of the message, that would require different logic.
