I found that doing data processing in Go was a bit cumbersome due to missing generics. Using a functional programming approach, data processing is easy because you can create new data by taking old data and specifying a transformation process. With Go, I had to manually handle the iteration through the old data's container object. Not a huge deal, but it felt like I was reinventing the wheel in every goroutine.
