Defer is the golang’s version of the more familliar finally statement of the try/catch block in languages like Java and C#. The defer allows you to perform actions when surrounding function returns or panics. Unlike finally blocks though it does not need to be placed at the bottom of the code block. You can also have multiple defer statements in a single function body. This allows for handy clean up of resources. It does have its downsides though. It does add overhead so using it everywhere might not be the best idea. ...

I won’t go into detail why inheritance is bad, but if you want an explanation Inheritance is Inherently Evil is a good read on that. All you want to achieve with inheritance can instead be done through composition and the use of interfaces. It also gets rid of generics. This means that the code you read will be clear and simple. It might be more verbose than many other languages but you also carry more control. ...
