算法练习以及帅气的一行代码

### 日常用到的一行代码

##### 数组随机打乱

const shuffleArray = (arr:any[]) => arr.sort(() => Math.random() - 0.5)

##### 数组去重

const getUnique = (arr:any[]) => [...new Set(arr)]

##### 数组的最大值、最小值、平均值、和

const max = (arr:number[])=> arr.reduce((a,b) => a>b?a:b);
const min = (arr:number[])=> arr.reduce((a,b) => a<b?a:b);
const average = (arr:number[]) => arr.reduce((a, b) => a + b)/arr.length;
const sum = (arr:number[])=>arr.reduce((a,b)=> a+b);

##### 数组排序

const ascending = (arr: number[]) => arr.sort((a, b) => a - b); // 升序
const decending = (arr: number[]) => arr.sort((a, b) => b - a); // 降序

##### 页面滚动

const scrollToTop = (element:HTMLElement) => element.scrollIntoView({ behavior: "smooth", block: "start" }) // 滚动到顶部
const scrollToBottom = (element:HTMLElement) => element.scrollIntoView({ behavior: "smooth", block: "end" }) // 滚动到底部

##### 复制内容到粘贴板

const copyToClipboard = (text:string) => navigator.clipboard.writeText(text);

##### 生成随机颜色

const generateRandomHexColor = () => "#" + Math.random().toString(16).slice(-6);
