How to start learning Go

Go, or Golang, is a compiled multi-threaded programming language developed by Google. Rob Pike and Ken Thompson started work on it in 2007 with the goal of creating a fast, productive, and fun language without losing readability and simplicity. And as a result, they came up with Go, a language designed to simplify and speed up software development.

In this article, I will talk about aspects of Golang that you should pay attention to first of all, as well as provide links to modern resources for learning this programming language, which are best suited for novice developers.

What to look for when learning Go

Let’s start with the basic concepts that are usually included in any Go training course:

  1. First of all, you need to be aware of structures (structures or structs) and compositions of structures (composition). In simple terms, the first is a way to group objects of different types into one variable, and the second is a way to combine simple objects and data types into more complex ones, which is ultimately needed to create reusable code segments, since in this case a more complex object can use the functions of its component parts. And this is the key point in Go.

  2. Another important aspect is functions and methods. In Go, functions are not associated with any type – unlike methods. Methods are essentially the same functions, but when defining them, you must specify the recipient – an argument of the type to which the method is attached.

  3. Errors in Go are returned and checked explicitly. The developer himself determines which errors the method can return and implements their handling on the calling side. If the program encounters an error that the developer did not foresee, then panic and recover are used. The first one fires when the code cannot solve the current problem and stops the application from running. Recover returns control in case of a panic. Then the application is restored and continues in normal mode.

  4. It is also necessary to pay attention to standard Go libraries: fmt, net/http and others. The name of the first comes from the word formatting, and it allows you to format basic strings, values, and other objects, display them on the screen, and receive data from the user. As for net/http, it is a system package that helps developers create web servers and clients.

  5. Go is a language strong static typing, that is, each variable has its own immutable type. This property contributes to the simplicity of the code, makes it easy to read, and in addition, minimizes the risk of errors due to inattention.

  6. Do not forget about competitiveness (or concurrency) – a form of computing when several instructions are executed, intersecting, within the same time period. In Go, it is provided by gorutin (goroutings) and channels (channels): the former are functions that run concurrently with other goroutines in the same address space, and channels allow you to transfer structured data from one goroutine to another. The main advantage of goroutines over threads is that they are lightweight, as you can run hundreds of thousands of these functions on the same machine.

  7. To clean up memory, Go, unlike some other general-purpose languages, provides garbage collector (garbage collector) – an algorithm that scans the code for objects that slow down its work, and removes them. It provides high speed of program execution and efficient use of resources.

  8. Concerning OOP, then Go loses a little to other languages ​​- for example, it has no classes and inheritance. There is an explanation for this – in this way the creators of Go achieved minimal redundancy and ensured high speed of program execution.

  9. In terms of code organization in Go, it consists of packageswhich are divided into modules. Modularity allows you to define a package with the desired functionality once and then use it repeatedly in different programs. Modular code not only helps with organization, but also with maintenance, testing, and, most importantly, dependency management to combat excessive application complexity.

  10. Go supports automatic testing using the testing package, which is used by most developers, but the language ecosystem includes many other testing libraries, each with its own specifics. Debugging it is also possible using the standard GDB module or its advanced alternative – Delve.

Now you know what to pay special attention to when learning the basics of Go. Now is the time to get into action, and I have a selection of resources for you to help you learn most effectively. This is my personal selection, but rest assured that every course and every book has already passed the test of time and thousands (even millions) of sophisticated students. Go!

Write your first Go code

As you know, the best way to learn is by doing, so after mastering the basics it is useful to take on the creation of real applications, and here I can advise you to focus on web development using Go, since this language allows you to solve many tasks related to the web. To do this, you first need to learn net/http, the standard package for building HTTP servers in Go. Put your knowledge to the test and try building and running a simple web server in Go. I think that after this you will want to dive even deeper into the topic, and here I can recommend studying the popular frameworks for web development in Go – Gin, Echo and Revel.


In conclusion, I want to say that you can start writing working code in Go in just a couple of days after learning it, however, in order to become a real specialist and use the features that it offers most effectively, you need a lot of patience, constant curiosity and complete immersion in details and features of the language. In this article, I’ve outlined the most important topics and concepts to learn first, and provided links to resources that I think will help you along the way the best.

Good luck!
