grabbing all of one value type from a collection

Question

I'm working on a Discord.js bot trying to add roles to mentioned users in a command. it stores all of the mention data for the message in a collection msg.mentions.users and looks something like this.

  '189920214777856000' => User {
 id: '189920214777856000',
 username: 'Warburp',
 discriminator: '2542',
 avatar: 'e83b4777a8abfd7f4cfc0f04761520b4',
 bot: false,
 status: 'online',
 game: null } }

What Id would like to do is collect all of the id's that were mentioned into an array so I can use a for loop too add them all to a role. Distinct is not recognized when I try to use it and find required I add a value and only finds exactly what I specify.

Collection.keyArray() is possibly what you're looking for. From what I understand msg.mentions.users is a Collection object mapping IDs to User objects. So something like this will give you an array of the user IDs:

msg.mentions.users.keyArray()
