Checks if two reactions are equal. This works by checking if the emoji

"equal".

.. describe:: x != y
|

Checks if two reactions are not equal.

Returns the reaction's hash.

Parameters
|
|
------------

limit: int

The maximum number of results to return.

reacted to the message.

after: :class:`abc.Snowflake`

--------
|
|
HTTPException

Getting the users for the reaction failed.
