Increasing Cohesion in Go with Generic Decorators
Cohesion is part of the low coupling, high cohesion principle that’s supposed to keep your code maintainable. While low coupling means few dependencies, high cohesion roughly translates to single responsibility. Highly cohesive code (a module or a function) is focused on a single purpose. Low cohesion means it does many unrelated things. I’ve written about coupling in the previous article on anti-patterns. Here are some tips on increasing cohesion in Go applications using the recently released generics.
