Using golog

Now that we understand what is available in the standard library, we want to explore the option of using a library that can provide us with more flexibility. We will look at the golog open source project (https://github.com/kataras/golog). The golog library is a dependency-free logging library that provides functionality such as leveled logging (INFO, ERROR, etc.), JSON-based output, and configurable color output.

Just for information purposes

WARN

ERROR
