if/else

Node.js

  1. const array = [1, 2]
  3. if (array) {
  4.   console.log('array exists')
  5. }
  7. if (array.length === 2) {
  8.   console.log('length is 2')
  9. } else if (array.length === 1) {
  10.   console.log('length is 1')
  11. } else {
  12.   console.log('length is other')
  13. }
  15. const isOddLength = array.length % 2 == 1 ? 'yes' : 'no'
  17. console.log(isOddLength)

Output

  1. array exists
  2. length is 2
  3. no

Go

  1. package main
  3. import "fmt"
  5. func main() {
  6.     array := []byte{1, 2}
  8.     if array != nil {
  9.         fmt.Println("array exists")
  10.     }
  12.     if len(array) == 2 {
  13.         fmt.Println("length is 2")
  14.     } else if len(array) == 1 {
  15.         fmt.Println("length is 1")
  16.     } else {
  17.         fmt.Println("length is other")
  18.     }
  20.     // closest thing to ternary operator
  21.     isOddLength := "no"
  22.     if len(array)%2 == 1 {
  23.         isOddLength = "yes"
  24.     }
  26.     fmt.Println(isOddLength)
  27. }

Output

  1. array exists
  2. length is 2
  3. no
