javascript - while 循环在 JavaScript 中在新行上打印元音和其他元素

Question

尝试按照单词出现的顺序在新行中打印单词中的任何元音。然后在打印所有元音后对每个常量执行相同的操作。

我尝试使用中断和开关盒，但代码不起作用。

function vowelsAndConsonants(s) {
    var atom = s.length;
    var i = 0;
    while (i <= atom)
    {
        if (s[i] === 'a' || s[i] === 'e' || s[i] === 'i' || s[i] === 'o' || s[i] === 'u') {
            console.log('\n' + s[i]);
        }
        else {
            console.log('\n' + s);
        }
    }

}

我希望输出如下:

a
i
o

然后按辅音出现的顺序排列:

t
p
r

您可以使用includes来检查给定字符串上的元音数组

const vowelsAndconsonants = str => {
  const vowels=['a','e','i','o','u'];
  //convert string to array and get rid of non alphabets as we are just interested on consonants and vowel
  const str_array=str.replace(/[^a-zA-Z]/g, '').split('');
  //pluck vowels
  const vowels_final=str_array.filter( a => vowels.includes(a.toLowerCase()));
  //pluck consonants
  const consonant_final=str_array.filter( a => !vowels.includes(a.toLowerCase()));
//to print any vowels from a word on a new line and then consonant in the order they appear. 
  return vowels_final.join('\n') + '\n' + consonant_final.join('\n');
}

console.log(vowelsAndconsonants('tEstOnlY and nothing else'))
console.log(vowelsAndconsonants('dry'))
console.log(vowelsAndconsonants('I love stackoverflow'))
