js给几个随机数组使它遍历并且去重

1. 生成随机数组

const randomArray = [];
const length = 10;
for (let i = 0; i < length; i++) {
  randomArray.push(Math.floor(Math.random() * length));
}

2. 遍历并去重

const uniqueArray = [];
randomArray.forEach((item) => {
  if (!uniqueArray.includes(item)) {
    uniqueArray.push(item);
  }
});
console.log(uniqueArray);
