Discord bot, deleting messages - discord.js

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).
