javascript - 返回最短单词和最长单词的长度差值(使用 for 循环)

Question

我想知道如何返回最短单词和最长单词的长度差值(使用 for 循环):

function findShort(s){

 s = s.split(" ");

   (for let i = 0; i < s.length; i++) {
   ******code goes here******
}

}

findShort("bitcoin take over the world maybe who knows perhaps");
findShort("turns out random test cases are easier than writing out basic ones"); 
});

有什么想法吗？如果有人也想尝试使用 map 或 reduce 之类的东西，我们也将不胜感激。

干杯!

将数组缩减为一对 short 和 long 值，并返回差值:

const findDelta = str => {
  const [long, short] = str.split(/\s+/)
    .reduce(([long, short], { length }) => [
      Math.max(long, length), // take the longest length
      Math.min(short, length) // take the shortest length
    ], [-Infinity, Infinity]) // init long with -Infinity and short with Infinity
    
  return long - short
}

console.log(findDelta("bitcoin take over the world maybe who knows perhaps"))
console.log(findDelta("turns out random test cases are easier than writing out basic ones"))
