Question: document is wrong?

[BigWestGang]

I read the document.
However, when you read the actual source code comment, only InitialLoad exists as a parameter.

• in https://favoriteposts.com/

/**
* favorites-user-favorites-loaded
* Fires after the user's favorites have loaded
* @param favorites - Array of post objects the user has favorited
* @param intial_load - Boolean 
*/
$(document).on('favorites-user-favorites-loaded', function(event, favorites, intial_load){
  // Do stuff here as needed
});

• in assets/js/favorites.js

* favorites-user-favorites-loaded: The user's favorites have been loaded. Params: intialLoad (bool)

Document information is old?
Or is it the wrong modification of this version?
