如何删除重复的数组在js中使用set和把每个项目在li标签..下面是我的代码

Question

const xx = [" 4", "9", "16"," 4", "9", "16"," 4", "9", "16"]
<ul> {(<li> {[...new Set(xx)]} </li>)} </ul>

const xx = ["4"， "9"， "4"， "9"， "4"， "9"， "16&;]

{(
• {…new Set(xx)]}
div)}

这里可以正常工作

const xx = [" 4", "9", "16"," 4", "9", "16"," 4", "9", "16"];
const set = [...new Set(xx)];
let html = '';
set.forEach(el => {
html += `<li>${el}</li>`;
});
document.querySelector("#list").insertAdjacentHTML('afterbegin', html);

<ul id="list"></ul>

您也可以对数组方法

执行相同的操作

const xx = [" 4", "9", "16"," 4", "9", "16"," 4", "9", "16"];
const html = [...new Set(xx)].map(el => `<li>${el}</li>`).join('');
document.querySelector("#list").insertAdjacentHTML('afterbegin', html);

<ul id="list"></ul>
