_.bindKey()
_.bindKey(object, key, [partials])
Creates a function that invokes the method at object[key] with partials prepended to the arguments it receives.
This method differs from _.bind by allowing bound functions to reference methods that may be redefined or don't yet exist. See Peter Michaux's article for more details.
The _.bindKey.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for partially applied arguments.
Arguments
object (Object): The object to invoke the method on.
key (string): The key of the method.
[partials] (...*): The arguments to be partially applied.
Returns
(Function): Returns the new bound function.
