Go for dummies

This is a very brief introduction to the Go programming language

The purpose

The purpose of this post is making use of some of the Go concepts and get some help to get started in working with Go


Why Go? I have some experience coding in Scala and recently I did a brief poc with Erlang… They both are nice (especially Erlang) but I wanted to try Go since awesome products are developed in it such as Docker or Consul. Beside Go syntax is lovely!

About the PoC

I just decided to develop a game as I thought It could be a good way to know some Go statements and data structures.


  • The pieces will be displayed in a 6 x 6 board.

  • Board will contain three type of letters: A or B or C and they all will be distributed randomly in the board

  • Once a position is discovered by the player this cannot be chosen again.

  • When the player finds a pair his scores is increased in 10 points, when the player doesn’t find a pair his scores is decreased in 2 points.

  • Game is over when there’s no more available board boxes.


Below a couple of pictures of the game



To sum up

  • Syntax is lovely, similar to C

  • Method can return more than one value, this is great.

  • Import other ‘classes’ (sorry but I have too much experience working with OOP programming languages) can be done using a single word import

  • Unused imports and variables will throw fails in the project compilation.

  • Below a sample of creating struct instances, the one will return a pointer and the second one an object. Do not forget we use pointers in Go.

  • The logo is so great! XD
