In the previous article we discussed the Builder pattern. There we noticed a drawback that we can't perform validation when assigning parameters. As a result, we are deprived of the ability to build a chain of methods. Let's look at another more interesting pattern - Functional options. There are different implementations with slight differences, but the basic idea is as follows
When we design API modules, one question may arise: how will the logic of working with optional parameters of our struct be organized? Effectively solving this problem can significantly increase the usability of our API. In this article I will give a concrete example from my practice in CRM development and how the Builder pattern helped me in this issue.
Interfaces are an important element of statically typed languages for writing functions with different input values. Here I will try to give an overview of how this feature is implemented in Go and how it affects the code. The most important basics and syntax are followed by a more detailed look at the idiomatic use of interfaces. Special attention is given to how dependencies in code can be avoided or how developers can reduce them. After all, this is one of the most important properties of interfaces.
One of the strangest things Go developers can do is to use a specific error type rather than an interface as the return type of a function. If you do, remember this is a very bad idea with unpredictable results.
Generics is a way of writing code that does not depend on the specific types used. Functions and types can now be written for any set of types. With generics, three important functionalities are added to the language:
According to Wikipedia, Go (or Golang) is a programming language that was developed by the Google team and first appeared in 2009. It was designed specifically for backend development and infrastructure projects. Go is an open source programming language that enables the production of simple, efficient, and scalable software.
At work and at home, I use the Linux operating system exclusively. But what kind of workplace can be without widgets on the desktop? So I decided to install and configure Conky. The application seemed very useful, but something was missing. Why not to add current exchange rates there and display fortunes? For these purposes, I decided to write a script. And since we are talking about a console application, everything was done on GO.

I see how many bloggers write about how important it is to say "No" and then often see comments such as "Excellent", "It is very important to set priorities correctly." An interesting point for me is that when someone writes that he learns to say no, this means that he already knows how to say yes.
