DAY18：Highest and Lowest

題目連結

Highest and Lowest

解法

Javscript

function highAndLow(numbers){
  const numbersArray = numbers.split(' ').map(Number);
  const maxNumber = Math.max(...numbersArray);
  const minNumber = Math.min(...numbersArray);
  return (`${maxNumber} ${minNumber}`)
}

Typescript

function highAndLow(numbers: string): string {
  const numbersArray: number[] = numbers.split(' ').map(Number);
  const maxNumber: number = Math.max(...numbersArray);
  const minNumber: number = Math.min(...numbersArray);
  return `${maxNumber} ${minNumber}`;
}

筆記

首先將原本傳入的number:string轉換成數字陣列
使用Math.max和Math.min可以快速找到最大值和最小值

最近開始練習Typescript
與Javascript交互比對可以更了解型別
