Example
- Typed collections
- Similar declaraction syntax
- Bunch of associated functions
Tag: Language
(Go Lang) Arrays (GBEN)
Example
- Like
Cdeclaration and index referencing and default values andlenand multi-dimensional - declaration of, inference and assignment to
b := [5]int{1, 2, 3, 4, 5}
- Not used much because yet to be explained
slicesare better
(Go Lang) Switch (GBEN)
Example
- Like C
- switch / case / default
- Multiple comma separated conditions per case
- case on interface type
- Interface types not yet introduced
(Go Lang) If/Else (GBEN)
Example
- Just like in
C- But with let-like bindings in declaration
- So last line would generate an error because num is out of scope
- But with let-like bindings in declaration
- No ternary
(Go Lang) For (GBEN)
Example
- Only looping construct
- Same as in
C
(Go Lang) Constants (GBEN)
Example
- Typical constants
constkeyword can appear anywhere, maybe declaring a type- Type given by explicit cast or use in context
(Go Lang) Variables (GBEN)
Example
- Typed variables are either declared explicitly or inferred
- Assignment is
= - Both multiple declaration and assignment
- Numeric initialize default to zero
:=→ declaration of, inference and assignment to
(Go Lang) Values (GBEN)
Example
- Numeric and logical operations seem to work as you would expect.
- The
,format for joining values is nice.
(Go Lang) GBEN: Hello World

Go has first class Unicode support. What do upper-case and lower-case mean when there is no such thing for the character? Does it fail with an error or not? How do you compare the size or length of Unicode characters?
fmt.Println("? Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo ")
? Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo
(Go Lang) Go by Example Notes (GBEN) Emacs Setup
Goal
Go by Example is Mark McGranaghan‘s “hands-on introduction to Go using annotated example programs”. Under the license I’m going to
- Convert all of the examples to Org-Mode Literate Programming documents
- Add, remove and modify them making it my personal notebook
- Add the tag GBEN to track them
- Refer to this post to provide attribution
