Go Tutorial

Master the basics and advanced features of the Go Programming Language.

If you want to learn Go, now is the perfect time! This tutorial is designed to help you get started with Go as quickly as possible. We’ll start with the basics and then dive into some of the more advanced features of the language.

Unlike other tutorials that only cover the basics like for-loops and if-statements, this tutorial will teach you how to harness the full power of Go’s concurrency model and interface-type systems.

Go is famous for being easy to learn but challenging to master. Through various programs, quizzes, and assignments, you’ll quickly grasp the language’s unique quirks.

Like any other programming language, the best way to learn Go is by writing code and building things. Therefore, this tutorial will give you many opportunities to do just that, encouraging you to work on your programs.

In this tutorial, you’ll:

  • Understand the basic syntax and control structures of Go.
  • Master the types in Go, especially if you are familiar with a dynamically typed language like JavaScript or Python.
  • Organize your code effectively using packages.
  • Apply Go’s concurrency model to build massively parallel systems.
  • Use the Go runtime to develop and compile projects.

Section 1. Getting Started with Go

Section 2. Basic Go

  • Variables – Learn how to declare and initialize variables in Go programs.
  • Constants – Represent values that cannot be changed during the execution of a program.
  • String – Learn how to manipulate strings effectively.

Section 3. Control Flow

  • If…else – Show you how to use the if…else statement to execute a code block based on one or more conditions.
  • Switch – Learn how to execute a branch by comparing a value with multiple possible values.
  • For loop – Execute a block of code repeatedly for a specified number of times or as long as a condition is true.
  • For range loop – Iterate over the elements of a collection such as an array or a slice.
  • Break – Stop a loop immediately
  • Continue – Skip the remaining code of the current iteration and start a new one.

Section 4. Functions

Section 5. More Go Data Structures

  • Arrays – Learn how to use arrays to hold a fixed number of elements with the same type.
  • Slices – Explain slices which are views to arrays but provide dynamic size.
  • Maps – Show you how to create a map that associates keys with values.
  • Structs – Learn how to create a struct, which is a composite type that includes one or more fields.

Section 6. Methods & Interfaces

  • Methods – Learn how to define methods on types including structs.
  • Interface – Show you how to use interfaces to write more flexible code that accepts different types as long as they implement the same interface.
  • Empty Interface: interface {}: Use empty interfaces to represent values of any type, which is quite flexible.

Section 7. Concurrency

  • Goroutines – Learn how to use goroutines to run functions concurrently.
  • Channels – Use channels to allow goroutines to exchange data.
  • Select – Show you how to use the select statement to manage multi-channel operations and process the first available channel.
