javascript - 使用带反引号和美元符号的 console.log() 打印变量

Question

我正在尝试使用反引号和美元符号打印数组中的变量，但不知何故它没有从数组中检索数据。

    var buz = {
      fog: 'stack',
      snow: 'white'
    };

    for (var key in buz) {
      if (buz.hasOwnProperty(key)) {
      console.log(`this is fog {$key} for sure. Value: {$buz[key]}`);
      } else {
        console.log(key); // toString or something else
      }
    }

这打印:

this is fog {$key} for sure. Value: {$buz[key]}
this is fog {$key} for sure. Value: {$buz[key]}

如何打印:

this is fog fog for sure. Value: stack
this is fog snow for sure. Value: white

?

你需要${expression}。有关详细信息，请参阅 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals

var buz = {
  fog: 'stack',
  snow: 'white'
};

for (var key in buz) {
  if (buz.hasOwnProperty(key)) {
  console.log(`this is fog ${key} for sure. Value: ${buz[key]}`);
  } else {
    console.log(key); // toString or something else
  }
}
