Automatically forwarded messages from a channel to its discussion group have the same available reactions as messages in the channel. Bots can't use paid reactions. Returns True on success.

Find out which reactions were added and removed in a message_reaction update. This method looks at ctx.messageReaction and computes the difference between the old reaction and the new reaction. It also groups the reactions by emoji reactions and custom emoji reactions. For example, the resulting object could look like this:

{
  emoji: ['👍', '🎉']
  emojiAdded: ['🎉'],
  emojiKept: ['👍'],
  emojiRemoved: [],
  customEmoji: [],
  customEmojiAdded: [],
  customEmojiKept: [],
  customEmojiRemoved: ['id0123'],
  paid: true,
  paidAdded: false,
  paidRemoved: false,
}

In the above example, a tada reaction was added by the user, and a custom emoji reaction with the custom emoji 'id0123' was removed in the same update. The user had already reacted with a thumbs up reaction and a paid star reaction, which they left both unchanged. As a result, the current reaction by the user is thumbs up, tada, and a paid reaction. Note that the current reaction (all emoji reactions regardless of type in one list) can also be obtained from ctx.messageReaction.new_reaction.

Remember that reaction updates only include information about the reaction of a specific user. The respective message may have many more reactions by other people which will not be included in this update.

Returns True on success.

Context.has is an object that contains a number of useful functions for probing context objects. Each of these functions can generate a predicate function, to which you can pass context objects in order to check if a condition holds for the respective context object.

For example, you can call Context.has.filterQuery(":text") to generate a predicate function that tests context objects for containing text:

const hasText = Context.has.filterQuery(":text");

if (hasText(ctx0)) {} // `ctx0` matches the filter query `:text`
if (hasText(ctx1)) {} // `ctx1` matches the filter query `:text`
if (hasText(ctx2)) {} // `ctx2` matches the filter query `:text`

These predicate functions are used internally by the has-methods that are installed on every context object. This means that calling ctx.has(":text") is equivalent to Context.has.filterQuery(":text")(ctx).
