$authorID

Returns message's author ID.

Usage

$authorID

Example

$nomention
This command was written by <@$authorID>!

Explanation

Discord uses this format: <@USER_ID> to mention user. For example, let's say that $authorID is equal to 246604909451935745. If we use this: <@$authorID>, it will be replaced with <@246604909451935745> and discord will interpret this as a mention (@Noituri).
