Many programs benefit from logging certain information about what is going on. Maybe some part of your code returned an error and you want to make note of some details in relation to that error. Perhaps you want to see who is sending requests to your server and you capture some info such as the ip address and what type of service sent the request.

Regardless of your reason for using it, logging tends to be a good thing to integrate into your program at some point or another.

Luckily, go has a basic log package in the standard library. While it lacks some features you may see in 3rd party logging frameworks, it can fulfill some basic use cases.

Check out the video tutorial where I go over some examples of using, not only the standard log package, but a useful 3rd party logging package called logrus
