The final thing we need to cover in the getValue method, provided by the defaultResponses, is the replacers parameter. This parameter can be either an array of objects or an object with embed values in them. We will provide two examples, one of each, to provide as much information as possible. Replacers in your message.json file are identified by brackets. Any value in-between {} will be treated as a replacer. In general, replacers are only needed if you have a dynamic value that will change from time to time, say if a different user uses the command, or you want to provide a random response.
