Intro to Go

For developers looking forward to learning Go

History

The Go programming language was created by some awesome developers at Google, generally they wanted a language that had 3 main properties:

  1. Fast compile time
  2. Ease of development
  3. Fast execution

All 3 of these were hard to find in a programming language, Go was created to be that language.

Go has all of the mentioned properties above.

  1. It has a very fast compile time.
  2. Ease of development as it reduces many of the complexities that come with C
  3. Fast execution

Installation

Go to https://golang.org/dl/ to download Go, follow the directions to setup your first go lang project.

Documentation

An important factor with working with Go is knowing your way around the documantation. Visit https://golang.org/doc/

Lessons

1. Intro to GO
  • Intro to go
  • Anatomy of a Go file
  • Declaring and assigning variables
  • Running go programs
2. Types in GO

  • Integers - int int8 int32 int64 ... var age int = 4

  • Float - float32 float64 var gpa float64 = 4.0

  • Strings "Pancakes" var flower string = "daisy"

  • Boolean - true false var canDrink bool = age > 21

  • Using relect Go package to check type of a variable var x = 10; reflect.TypeOf(x)

  • Type conversion in Go var y = float64(x) fmt.println(reflect.TypeOf(y))

3. IF ELSE Conditional statements

  • if condition { fmt.println("Awesome") }

  • if condition { fmt.println("Awesome") } else if condition { fmt.println("cool") }

  • Variable scoping with IF statements if err := someFunction(); err != nil { fmt.println(err) }

4. FOR LOOPS
  • for i := 0; i <= 100; i++ { fmt.Println(i) } Prints 0 to 100
