Javascriptの練習をしました
私が練習したJavaScriptコードを説明します
for (let i = 0; i < mise_list.length; i++) {
if (mise_list[i]['IDEX_MVL'] < 40) {
console.log(mise_list[i]['MSRSTE_NM'])
}繰り返し文で始まる
変数＃ヘンスウ＃
i = 0
i Mise listよりlengthが大きいとiが1つずつ増えていきます
mise list[i]の[IDEX MVL]が40未満の場合
console.log mise list[i]に[MSRSTE NM]領域名を表示
コード作成後のコンソール。ロゴで確認した答え
