用最少的代码做到数组去重、排序

数组去重

代码块

    const oldArr = [1,3,5,7,9,2,3,5,4,1];    const newArr = [...new Set(oldArr)];    console.log(newArr);//[1,3,5,7,9,2,4]

数组去重+排序

代码块

    const oldArr = [1,3,5,7,9,2,3,5,14,1];    const newArr = [...new Set(oldArr)].sort((a,b)=>a-b);    console.log(newArr);//[1,2,3,5,7,9,14]
