Discord bot, deleting messages

Question

I'm new to discord bots. I have a script that gives members a role if the join a VC, that way they can see a Text channel. I want the channel to be cleared out.

This is what I have so far:

module.exports = (client) => {
    // Clears chat?
    client.on('messageCreate', async function (message) {
        if (message.channel.id === '965002780878176286') { //Bar-Chat
            var CheckMinutes = 1, CheckBAR = CheckMinutes * 60 * 1000;
            setInterval(function () {
                message.channel.messages.fetch({ limit: 100 }).then(function (deleteThese) { message.channel.bulkDelete(deleteThese); })
            }, CheckBAR);
        };
        if (message.channel.id === '965266326828490792') { //Just-Chat
            var CheckMinutes = 1, CheckJC = CheckMinutes * 60 * 1000;
            setInterval(function () {
                message.channel.messages.fetch({ limit: 100 }).then(function (deleteThese) { message.channel.bulkDelete(deleteThese); })
            }, CheckJC);
        };
        if (message.channel.id === '965266431589613618') { //Game-Chat #1
            var CheckMinutes = 1, CheckGC1 = CheckMinutes * 60 * 1000;
            setInterval(function () {
                message.channel.messages.fetch({ limit: 100 }).then(function (deleteThese) { message.channel.bulkDelete(deleteThese); })
            }, CheckGC1);
        };
        if (message.channel.id === '965266551857115156') { //Game-Chat #2
            var CheckMinutes = 1, CheckGC2 = CheckMinutes * 60 * 1000;
            setInterval(function () {
                message.channel.messages.fetch({ limit: 100 }).then(function (deleteThese) { message.channel.bulkDelete(deleteThese); })
            }, CheckGC2);
        };
        if (message.channel.id === '965266660003049472') { //Game-Chat #3
            var CheckMinutes = 1, CheckGC3 = CheckMinutes * 60 * 1000;
            setInterval(function () {
                message.channel.messages.fetch({ limit: 100 }).then(function (deleteThese) { message.channel.bulkDelete(deleteThese); })
            }, CheckGC3);
        };
    });
}

Is there a better way of doing this? Don't mind the short timer (still testing and don't want to wait like 15/30 mins).
