JSHint is now a fair bit stricter, and is now correctly checking files in `mods/`. The code has been fixed to match the new stricter standards. JSHint has now caught its second actual bug: Gen 5 Pinap Berry was Ice instead of Grass.

/**

* Users
|
|
* Pokemon Showdown - http://pokemonshowdown.com/
|
|
*
|
|
* Most of the communication with users happens here.
|
|
*
|
|
* There are two object types this file introduces:
|
|
* User and Connection.
|
|
*
|
|
* A User object is a user, identified by username. A guest has a
|
|
* username in the form "Guest 12". Any user whose username starts
|
|
* with "Guest" must be a guest; normal users are not allowed to
|
|
* use usernames starting with "Guest".
|
|
*
|
|
* A User can be connected to Pokemon Showdown from any number of tabs
|
|
* or computers at the same time. Each connection is represented by
|
|
* a Connection object. A user tracks its connections in
|
|
* user.connections - if this array is empty, the user is offline.
|
|
*
|
|
* Get a user by username with Users.get
|
|
* (scroll down to its definition for details)
