JavaScript 模板字符串替换字符串拼接

$('#result').append('He is ' + person.name + ' and we wish to know his ' + person.age + '. That is all');

使用模板字符串可以简化代码，使其更易读。以下是使用模板字符串的示例：

$('#result').append(`He is ${person.name} and we wish to know his ${person.age}. That is all`);

模板字符串使用反引号（`）括起来，变量使用 ${} 包裹。这样可以更直观地表达字符串拼接逻辑，提高代码可读性。
