const person = "Mike";
const age = 28;

function myTag(strings, personExp, ageExp) {
  const str0 = strings[0]; // "That "
  const str1 = strings[1]; // " is a "
  const str2 = strings[2]; // "."

  const ageStr = ageExp > 99 ? "centenarian" : "youngster";

  // 我们甚至可以返回使用模板字面量构建的字符串
  return `${str0}${personExp}${str1}${ageStr}${str2}`;
}

const output = myTag`That ${person} is a ${age}.`;

console.log(output);
// That Mike is a youngster.
