const shuffleArray = (arr) => arr.sort(() => Math.random() - 0.5) 
// 测试
const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
console.log(shuffleArray(arr))

const copyToClipboard = (text) =>
  navigator.clipboard?.writeText && navigator.clipboard.writeText（text）
// 测试
copyToClipboard("Hello World!")

const getUnique = (arr) => [...new Set(arr)]
// 测试
const arr = [1, 1, 2, 3, 3, 4, 4, 5, 5];
console.log(getUnique(arr))

const isDarkMode = () =>
  window.matchMedia &&
  window.matchMedia("(prefers-color-scheme: dark)").matches
// 测试
console.log(isDarkMode())

const scrollToTop = (element) =>
  element.scrollIntoView({ behavior: "smooth", block: "start" })

const scrollToBottom = (element) =>
  element.scrollIntoView({ behavior: "smooth", block: "end" })

const generateRandomHexColor = () =>
  `#${Math.floor(Math.random() * 0xffffff) .toString(16)}`;
