Exercises for Programmers: 57 Challenges to Develop Your Coding Skills (Brian P. Hogan 著、Pragmatic Bookshelf)のChapter 6(Repetition)にミスがあるっぽいから報告、提出してみた。

コード(Emacs)

main.go

package main

import "fmt"

func main() {
 fmt.Println("before")
 counter := 5
 for counter <= 1 {
  fmt.Println(counter)
  counter--
 }
 fmt.Println("after")
 counter1 := 5
 for counter1 >= 1 {
  fmt.Println(counter1)
  counter1--
 } 
}

入出力結果(Terminal)

main.js

console.log('before');
for (var counter = 5; counter <= 1; counter--) {
    console.log(counter);
}
console.log('after');
for (var counter = 5; counter >= 1; counter--) {
    console.log(counter);
}
