ClientUtil is a class filled with utility methods.
It is available on your client as client.util.

There are three "groups" of resolver methods for finding or checking Discord-related things.
They allow you to, for example, find a user named 1Computer from an input of comp.

• resolve <thing>

  • e.g. resolveUser, resolveChannel, etc.
  • Finds an Discord-related object from a collection of those objects.

• resolve <things>

  • e.g. resolveUsers, resolveChannels, etc.
  • Filters Discord-related objects from a collection of those objects.

• check <thing>

  • e.g. checkUser, checkChannel, etc.
  • Used for the above methods, checks if a string could be referring to the object.

There are a bunch of other things you may find useful:

• embed, attachment, and collection
  • Shortcuts for MessageEmbed, MessageAttachment, and Collection.
• resolvePermissionNumber
  • Converts a permission number to an array of permission names.
