How do you make some bot commands only work in some discord channels - discord

Question

This is my first time using js. I need to ban a certain word in a certain channel. I don't want the message to be deleted if it is not in the specific channel.
For Example:
I want to ban the word "goodbye" in the #greeting channel
BUT
I don't want to ban the word "goodbye" In the #farewell channel
How would I go about this?
Thanks.
By the way I wanted to use example code, but none of it made any sense.

I wrote a simple example for you on how to achieve this:
const Discord = require("discord.js");
const Client = new Discord.Client();
const ForbiddenWords = {
"ChannelID": ["goodbaye", "bye"] // Greeting channel
};
Client.on("ready", () => {
console.log(`${Client.user.tag} is ready!`);
});
Client.on("message", (message) => { // Fired when the bot detects a new message.
if (message.author.bot) {return false}; // Checking if the message author is a bot.
if (ForbiddenWords[message.channel.id]) { // Checking if the current channel has any forbidden words in the ForbiddenWords Object
if (ForbiddenWords[message.channel.id].some(word => message.content.toString().toLowerCase().includes(word))) { // Checking if the message contains any forbidden words
message.delete(); // Deleting the message.
};
};
});
Client.login(process.env.DISCORD_AUTH_TOKEN);
