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: ['π', 'π']
emojiAdded: ['π'],
emojiKept: ['π'],
emojiRemoved: [],
customEmoji: [],
customEmojiAdded: [],
customEmojiKept: [],
customEmojiRemoved: ['id0123'],
}
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, which
they left unchanged. As a result, the current reaction by the user is
thumbs up and tada. Note that the current reaction (both emoji and custom
emoji 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
An object containing information about the reaction update
