用于在单行中显示文本的 Javascript 代码

Question

我正在上在线类(class)，我有一个程序要解决。我已经编写了代码并且它显示了正确的输出，但我需要在一行中打印这些行。任何人都可以帮助我。

如何在一行中显示多行文本。我写的代码如下:

var num = 99;

while (num >= 1) {
  if (num > 2) {
    console.log("" + num + " bottles of juice on the wall! " + num + " bottles of juice! Take one down, pass it around... " + (num - 1) + " bottles of juice on the wall!");
  } else if (num === 2) {
    console.log("" + num + " bottles of juice on the wall! " + num + " bottles of juice! Take one down, pass it around... " + (num - 1) + " bottle of juice on the wall!");
  } else {
    console.log("" + num + " bottle of juice on the wall! " + num + " bottle of juice! Take one down, pass it around... " + (num - 1) + " bottle of juice on the wall!");
  }

  num = num - 1;
}

作为@Nisarg Shah在评论中提到，您可以在循环外声明一个全局变量，循环内的代码不断添加。

一旦循环结束，代码可以使用 console.log 将存储在变量中的字符串输出为一行。

var output = "";

var num = 99;

while (num >= 1) {
  var pluralSuffix = num != 1 ? "s" : "";
  var nextNum = num - 1;
  var nextPluralSuffix = nextNum != 1 ? "s" : "";

  output += num + " bottle" + pluralSuffix + " of juice on the wall! " + num + " bottle" + pluralSuffix + " of juice! Take one down, pass it around... " + nextNum + " bottle" + nextPluralSuffix + " of juice on the wall! ";

  num = nextNum;
}

console.log(output);
