Exploring Golang

A repository focused on learning and practicing Golang

Go (golang)

1. Strong and statically typed
2. Excellent community
3. Key features
   • Simplicity
   • Fast compile times
   • Garbage collected
   • Built-in concurrency
   • Compile to standalone binaries

Variables

Agenda:

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

Variable declaration:

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

Cant 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 acronyms (HTTP, URL)
• As short as reasonable
  • Longer names for longer lives

Type conversions:

• DestinationType(variable)
• Use (strconv) package for string

Primitives

Agenda:

• Boolean type
• Numeric types
  • Integers
  • Floating point
  • Complex numbers
• Text types
