The Single Responsibility Principle (SRP) is a software design principle that states that a software module or component should have only one reason to change. This means that a module or component should have a single, narrowly defined responsibility and all of its features should be related to that responsibility. In Go, the SRP can be applied at both the package and the function level. At the package level, it’s important to consider what a package should be responsible for....
