This document discusses decision making in Golang. It provides an overview of loops including for, while, break, continue, and nested loops. It also covers conditionals such as if, else if, else, switch statements, and logical operators. Code examples are provided for each concept via links to an online Golang playground. The author is identified as Sangam Biradar, a Docker community leader who writes tutorials on Golang.

Package reflect implements run-time reflection, allowing a
program to manipulate objects with arbitrary types. The typical
use is to take a value with static type interface{} and extract its
dynamic type information by calling TypeOf, which returns a
Type.
A call to ValueOf returns a Value representing the run-time
data. Zero takes a Type and returns a Value representing a zero
value for that type.

- 11. ● rune ● A rune is a type meant to represent a Unicode code point. ● The rune type is an alias for int32, and is used to emphasize than an integer represents a code point. ● ASCII defines 128 characters, identified by the code points 0–127. It covers English letters, Latin numbers, and a few other characters. ● Unicode, which is a superset of ASCII, defines a codespace of 1,114,112 code points. Unicode version 10.0 covers 139 modern and historic scripts, as well as multiple symbol sets. ● Note that a string is a sequence of bytes, not runes. ● However, strings often contain Unicode text encoded in UTF-8, which encodes all Unicode code points using one to four bytes, and Go source code is always encoded in UTF-8. This encoding was in fact designed by Ken Thompson and Rob Pike, two of the main creators of Go.
