尝试按出现的顺序在新行上打印单词中的任何元音。 然后在打印完所有元音后对每个常量执行相同的操作。
我尝试过使用中断和开关盒，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
然后是辅音出现的顺序：
t
p
r

我们也可以使用以下代码解决问题。 [ Hackerrank Day2 解决方案 ]
function vowelsAndConsonants(s) {
// Create an array of vowels
const vowels = ['a','e','i','o','u'];
// Split up the String and Convert it to an Array
const letters = s.split('');
// Check for vowels
for(let i in letters){
if(vowels.includes(letters[i])){
// Print vowels on a new line for each characters.
console.log(letters[i]);
}
}
// Check for consonants
for(let i in letters){
if(!(vowels.includes(letters[i]))){
// Print consonants on a new line for each characters.
console.log(letters[i]);
}
}
}

在下面的帮助下，我们可以用简单的方法来区分元音和辅音
let strOne = "javascriptloopsAI"; // take any string
//String convert into lower case
var str = strOne.toLowerCase();
let vowelarr = ['a','e','i','o','u']; // use vowels array
// here's we are splitting str string with space.
let strArr = [...str];
var html='';
var htmlV='';
//for loop for strArr
for (i = 0; i < strArr.length; i++)
{
let field='';
//for loop for vowelarr
for (j = 0; j < vowelarr.length; j++)
{
if(strArr[i]==vowelarr[j])
{
field=strArr[i];
htmlV += strArr[i]+'</br>' // adding only vowels in htmlv variable
}
}
if(strArr[i]!=field)
{
html += strArr[i]+'</br>' //adding only consonants in htmlv variable

我们可以简单地使用正则表达式来匹配元音和辅音，然后打印它们。
下面是工作代码sn-p：
function vowelsAndConsonants(s) {
var vw =s.match(/[aeiouAEIOU]+?/g); //regular expression to match vowels
var con=s.match(/[^aeiouAEIOU]+?/g); //regular expression to not match vowels, ie. to match consonants
printOnConsole(vw); //print vowels
printOnConsole(con); //print consonants
}
//function to print values on console.
function printOnConsole(arrPrint){
for(var i=0;i<arrPrint.length;i++){
console.log(arrPrint[i]);
}
}

所以这是我使用的最终代码。感谢 Dash 和峰会的帮助。我结合了他们的两个代码。
// This is the function with the parameter which will have the input.
function vowelsAndConsonants(s) {
// This lists, all the vowels. Since I know the input is all lowercase, there is no need for uppercase. A lowercase method could also be used.
const vowels = ['a', 'e', 'i', 'o', 'u'];
// The input is split up to avoid printing the entire string, and is stored in a variable.
var letters = s.split('');
// An array to hold the vowels is created.
var vowelsFound = [];
// An array to hold the consonants is created.
var consonantsFound = [];
// Loops through all the split up characters held in the letters variable.
for (var i in letters) {
// If statement tests by using include to see if any of vowels match the i looper.
if (vowels.includes(letters[i])) {
//If any vowels do match, then they get added to the end of the vowelsFound array,
然后将其向上推，以便可以按照它们出现的顺序打印。
vowelsFound.push(letters[i]);
//The same process is used for the consonants.
} else {
consonantsFound.push(letters[i]);
}
}
//Prints the vowels in their order, on a new line for each character.
console.log(vowelsFound.join('\n'));
console.log(consonantsFound.join('\n'));
}

您可以使用包含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'))

您的主要问题是您决定在检查每个字母时是否应该打印。结果输出实际上是初始字符串。
虽然 sumit 的回答可以解决问题，但我会这样做，因为它要求您只遍历字母一次：
const vowelsAndConsonants = (str) => {
const vowels = ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'];
// Check for vowels
var letters = str.split('');
var vowelsFound = [], consonantsFound = [];
for (var i in letters) {
if (vowels.includes(letters[i])) {
vowelsFound.push(letters[i]);
} else {
consonantsFound.push(letters[i]);
}
}
console.log("Vowels:", vowelsFound.join(""));
console.log("Consonants:", consonantsFound.join(""));
}
var str = "ThisIsATest";
