function dropRightWhile(array, predicate, thisArg) {
	      return (array && array.length)
	        ? baseWhile(array, getCallback(predicate, thisArg, 3), true, true)
	        : [];
	    }
Creates a slice of `array` excluding elements dropped from the end.
Elements are dropped until `predicate` returns falsey. The predicate is
bound to `thisArg` and invoked with three arguments: (value, index, array).

If a property name is provided for `predicate` the created `_.property`
style callback returns the property value of the given element.

If a value is also provided for `thisArg` the created `_.matchesProperty`
style callback returns `true` for elements that have a matching property
value, else `false`.

If an object is provided for `predicate` the created `_.matches` style
callback returns `true` for elements that match the properties of the given
object, else `false`.

@param {Array} array The array to query.
@param {Function|Object|string} [predicate=_.identity] The function invoked
 per iteration.
@param {*} [thisArg] The `this` binding of `predicate`.
@returns {Array} Returns the slice of `array`.
@example

  return n > 1;
});
// => [1]

var users = [

// using the `_.matches` callback shorthand

// => ['barney', 'fred']

// using the `_.matchesProperty` callback shorthand
_.pluck(_.dropRightWhile(users, 'active', false), 'user');
// => ['barney']

// using the `_.property` callback shorthand
_.pluck(_.dropRightWhile(users, 'active'), 'user');
