I wrote a series of entries trying to serve as a guide to the Go programming language. This tutorial requires you to know at least the basis of programming, so it’s probably a good idea to read this only if you’re learning Go as your second or third programming language. This content goes from Go’s basic syntax to advances uses as signal catching or containerization.

## Go language introduction and Basic Syntax

Introduction to the Go programming language, native data types, variables, the controversy around this language, the good, the bad, the ugly and even a glimpse at its popular, and sometimes hated, mascot.

[Go, coding language, introduction to variables and data types](https://coffeebytes.dev/en/go-programming-language-introduction-to-variables-and-data-types/)

How to create go functions and pass arguments to them, along with the basis of the fmt package used to print text on the screen

[Go: functions, arguments and the fmt package](https://coffeebytes.dev/en/go-functions-arguments-and-the-fmt-package/)

Master the different type of loops that exist in go, learn how to use flow control to execute your code conditionally and learn about the break, continue and defer clauses.

[Go: loops for, break, continue, defer, if and else](https://coffeebytes.dev/en/go-cycles-or-loops-for-break-continue-defer-if-and-else/)

Create arrays and slices and know their differences and how to iterate over them correctly using range.

[Go: slices and arrays, basic characteristics and most common uses](https://coffeebytes.dev/en/go-slices-and-arrays-basic-characteristics-and-most-common-uses/)

Learn how do map or dictionaries work internally, the different ways to create them and how to iterate over them using range.

[Golang maps or dictionaries](https://coffeebytes.dev/en/golang-maps-or-dictionaries/)

Read about the main differences that exist between string, runes and bytes in go, how they work internally and their main related methods.

[Go: string runes and bytes explained](https://coffeebytes.dev/en/go-string-runes-and-bytes-explained/)

## Go Programming Language Tutorial: Object oriented programming

Go doesn’t have classes, but you can emulate OOP features (polimorfism, inheritance and encapsulation) using go structs.

[Go: Structs, inheritance, polymorphism and encapsulation](https://coffeebytes.dev/en/go-structs-inheritance-polymorphism-and-encapsulation/)

How to handle and import and reference packages and modules in go.

[Go: package import and module management](https://coffeebytes.dev/en/go-package-import-and-module-management/)

## Go Programming Language Tutorial: Concurrency and Corroutines

The feature that makes go stand out: concurrency and goroutines, learn how to create and handle them.

[Go: introduction to goroutines and concurrency](https://coffeebytes.dev/en/go-introduction-to-goroutines-and-concurrency/)

Here I explain you how to communicate goroutines through channels and the main principles to take care of when working with concurrent code.

[Go: use of channels to communicate goroutines](https://coffeebytes.dev/en/go-use-of-channels-to-communicate-goroutines/)

Understand the concept of deadlocks in the context of working with goroutines, how to avoid them and what causes this cumbersome problem.

[Go: channels, understanding the goroutines deadlocks](https://coffeebytes.dev/en/go-channels-understanding-the-goroutines-deadlocks/)

The basics of race conditions when working with concurrent code and how to prevent them. Create race condition resistant code using mutexes in Go

[Go: race conditions on goroutines and mutexes](https://coffeebytes.dev/en/go-race-conditions-on-goroutines-and-mutexes/)

## Go Programming Language Tutorial: Testing and Logging

The basis of go testing and coverage capabilities.

[Go: basic testing and coverage](https://coffeebytes.dev/en/go-basic-testing-and-coverage/)

How to profile and examine code performance using go.

[Go: profiling or basic profiling of CPU usage](https://coffeebytes.dev/en/go-profiling-or-basic-profiling-of-cpu-usage/)

How to use the default logging library in go programming language.

[Logging with the standard library in Go](https://coffeebytes.dev/en/logging-with-the-standard-library-in-go/)

## Go Applications

How to catch signals and process them in go to end your code execution in an elegant and safe way.

[Go: Handling Signals for Closing Applications](https://coffeebytes.dev/en/go-handling-signals-for-closing-applications/)

Learn how to handle SQL migrations using go’s migrate library

[Go Migration Tutorial with migrate](https://coffeebytes.dev/en/go-migration-tutorial-with-migrate/)

The basis of go’s reflection library and how to create flexible code that deals with unknown types

[Go with Reflect: Boost Your Code's Flexibility](https://coffeebytes.dev/en/go-with-reflect-discover-how-reflect-can-boost-your-programs-flexibility/)

Did you know that Docker is written in Go? Have you ever wondered how does a docker container works internally? Well I explain all the concepts that you need to know here in order to create your own containerization technology.

[How Does a Docker Container Work Internally?](https://coffeebytes.dev/en/how-does-a-docker-container-work-internally/)

I explain the worker pool design pattern in go and how to take advantage of Go’s concurrency and this design pattern to limit the amount of resources that your application uses.
