Go is an strong and statically typed. It has an excellent community. golangbridge.org is a good example

Key features

Go is focus on server side and not on clients

Variable Topics

• Variable declaration
• Redeclaration and shadowing
• Visibility
• Naming conventions
• Type conversions

Three different ways to declare a variable:

var foo int // Use when the value is not known at the moment
var foo int = 42 // Use when the compiler might get it wrong
foo := 42 // Most use. Works inside a block not at the package level

Three level of visibility for a variable

Package level with lower case

Global with capitalize

Variable at block lowercase

Single letter for short lived variables

Lower names for long lived variables using camelCase

To convert to string using strconv function

Summary

• var foo int
• var foo int = 423
• foo := 42

Normally the third version is used. The second version is used when the compiler is going to guess it wrong. The first version is used when the value is not known right away
Can’t redeclare variables, but can shadow them. All variables must be used

Visibility

• lower case first letter for package scope.
• upper case first letter to export.
• no private scope

Naming conventions

• Pascal or camelCase
  • – Capitalize Acronyns(HTTP, URL).
• As short as reasonable
  • – longer names for longer lives

Type conversions

• destination Type(variable).
• use strconv package for strings
