Today’s knowelege is quite simple:

Key Concepts

if

• Basic form

  for condition {
    // body
  } else {
    // body
  }

• Parentheses are unnecessary and not idiomatic

  for n > 0 {
    fmt.Println("Positive")
  }

switch

• Basic form

  day := 3
  
  switch day {
  case 1:
    fmt.Println("Monday")
  case 2:
    fmt.Println("Tuesday")
  default:
    fmt.Println("Unknown")
  }

• No break needed

• Multiple conditions

  score := 85
  
  switch {
  case score >= 90:
      fmt.Println("A")
  case score >= 80:
      fmt.Println("B")
  case score >= 70:
      fmt.Println("C")
  default:
      fmt.Println("D")
  }

for

• there’s no while in go

• for i := 0; i < 5; i++ {
    fmt.Println(i)
  }
