<h2>JavaScript 模板字面量</h2>

<p>模板字面量使用反引号 (``) 来定义一个字符串:</p>

<div id="demo"></div>

<p>Internet Explorer 不支持模板字面量。</p>

<script>
let header = "";
let tags = ["RUNOOB", "GOOGLE", "TAOBAO"];

let html = `<h2>${header}</h2><ul>`;
for (const x of tags) {
  html += `<li>${x}</li>`;
}

html += `</ul>`;
document.getElementById("demo").innerHTML = html;
</script>

</body>
