使用JavaScript生成罗马字符的实例代码

roman() {
 return new Array(30).fill('Ⅰ').map((lastLetter, i) => {
  return String.fromCharCode(lastLetter.charCodeAt(0) + i)
 })
}

var data = {
  ↈ: 100000,
  ↂↈ: 90000,
  ↇ: 50000,
  ↂↇ: 40000,
  ↂ: 10000,
  Ⅿↂ: 9000,
  ↁ: 5000,
  Ⅿↁ: 4000,
  Ⅿ: 1000,
  ⅭⅯ: 900,
  Ⅾ: 500,
  ⅭⅮ: 400,
  Ⅽ: 100,
  ⅩⅭ: 90,
  Ⅼ: 50,
  ⅩⅬ: 40,
  Ⅹ: 10,
  Ⅸ: 9,
  Ⅷ: 8,
  Ⅶ: 7,
  Ⅵ: 6,
  Ⅴ: 5,
  Ⅳ: 4,
  Ⅲ: 3,
  Ⅱ: 2,
  Ⅰ: 1
 } 
function g(num){
 var roman = ''
 if(num > 30000) return false
 var arr = []
 for (i in data) {
  while (num >= data[i]) {
   roman += i;
   num -= data[i];
  }
 }
 return roman
}
let arr = []
for (let index = 1; index < 26; index++) {
 arr.push(g(index))
}
console.log(arr)
