Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository. Loading history...

Methods can only be called on objects. This check looks for methods being called on variables that have been inferred to never be objects. Loading history...
