配列内の文字列を置換する

Last updated at Posted at 2020-11-24

#配列内の文字列を置換したい

userNameをたけしくんにする覚えがきです

index.js
const array = ["userNameくんかっこいいよね","userNameくんどこに住んでるの" ,"userNameくん乳首透けてるよ"]
index.js
  //配列を展開
  array.forEach((text) => {
    //指定した文字列が入っているか判断する(userName)
      const stringInUserName = text.includes("userName");
      if (stringInUserName) {
  //tureならuserNameをたけしくんにする
        text = text.replace("userName", "たけし");
      }
      return text;
    });
index.js
  たけしんくんかっこいいよね たけしくんどこにすんでるの たけしくん乳首透けてるよ

以上
