(Discord.js) Delete channels with specified text in name of Channel

Question

Basically as the title says. I'm wondering if there's a way of deleting all channels that contain a specific string for their name

Eg 18876557 -old

On command, delete all channels that names contain the string -old .

Answer 1

You can use Array.prototype.forEach() and Channel.delete()

// iterate a function through all channels in the guild
guild.channels.cache.forEach((channel) => {
  if (guild.name.includes('-old')) // if the string '-old' is found within the channel name
    channel.delete() // delete the channel
      .then(() => console.log(`Deleted ${channel.name}`))
      .catch((e) => console.log(`Could not delete ${channel.name} because of ${e}`)) // handle any errors
});

Answer 2

This is pretty easy, you just need to loop through the guild channels:

for (let channel of guild.channels.cache) {
    if (channel.name.includes("-old")) channel.delete();
}
