Notes About Go (part 1)

This is - probably - a series of short notes about Go during my learning journey. There might be some errors and things I got wrong here and there that I maybe fix later during my learning journey or maybe I don’t.

Variables


:=	Deceleration (first time)
=	Assignment

Note: Short deceleration := can assign variables too BUT has to declare 1 new variables at least. For example:

// Correct

in, err := o.Open(file)
out, err := o.Create(file)

// Wrong (won't compile)

in, err := o.Open(file)
in, err := o.Create(file)

Scope

Go Variables Scope Diagram

Go Routines

Create a channel
```
 ch := make(chan String)
```
Call a function with go prefixed and pass the channel variable as an argument.
```
 go myFunc(ch)
```
To receive output from a channel you can do something like:
```
 fmt.Println(<- ch)
```
To send things to the channel using you can do something like:
```
 ch <- "String
```

fmt

Printf variables referencing and octal numbers:

o := 0700 // Octal numbers can be defined with `0` prefixed 
fmt.Printf("%d  %[1]o  %#[1]o", o) // 448  700  0700
