Error handling in Go often puzzles beginners and those coming from other programming languages. In this post, we differentiate between errors (`error`) and exceptions (`panic`), discuss what makes an error "good" (easy to check and debug), and introduce a common way to make errors "good" — using `fmt.Errorf()`.

This article is for those who have some programming background and intend to learn Golang as a second language. I hope to provide some direction for your learning journey.
