#3 year of languages - go

So, I decided to try go - a cool programming language developed by google.

This language has been on my mind ever since some silly recruiter tried to recruit me for a golang job after looking through my github repositories and stumbling on the "go" project. He clearly hadn't looked very carefully, because:

  1. It wasn't written with golang - it was an implementation of the game "go"
  2. A large part of the functionality has been broken since before then, due to the PeerJS maintainers discontinuing their service and the fact I have been to lazy to fix it up

I've decided to confuse matters a little more - I've written a crude console app for playing the game "go" in golang.

I followed the following tutorials:

  1. How to write go code
  2. A tour of go
  3. Structs in go instead of classes

What I like about go

I really like being able to easily return multiple values from a single function. It feels very neat.

package main

import "fmt"
func getSomeNumbers() (int, int, int){
	return 6, 9, 42

func main(){
	a, b, c := getSomeNumbers()
	fmt.Println(a, b, c)

I also like the way errors are handled in go. Developing in go felt like I was forced to think about what I should do if an error occurs - I wasn't allowed to leave it till later (and obviously forget about it). They have clearly thought this aspect out and I look forward to seeing other languages eventually adopt this approach.

Furthermore, I enjoyed the tooling available in Visual Studio Code for go. It was ridiculously annoying at first, popping up at the top with suggestions for things I should download and not understanding that when I closed these suggestions, I wanted them to stay closed. However, I eventually succumbed to the pressure and downloaded all these extra things. They instantly improved my productivity and I can say they changed development in go from an interesting project to a whole load of fun.
