So here is the final code that I used. Thank for the help Dash and summit. I combined both of their codes.
// 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,which then get pushed up, so that it can be printed in the order they appear.
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')); }Javascript Online Compiler

About Javascript
Javascript(JS) is a object-oriented programming language which adhere to ECMA Script Standards. Javascript is required to design the behaviour of the web pages.
Key Features
- Open-source
- Just-in-time compiled language
- Embedded along with HTML and makes web pages alive
- Originally named as LiveScript.
- Executable in both browser and server which has Javascript engines like V8(chrome), SpiderMonkey(Firefox) etc.
Syntax help
variable declaration
var | Var is used to declare variables(old way of declaring variables) | Function or global scope |
let | let is also used to declare variables(new way) | Global or block Scope |
const | const is used to declare const values. Once the value is assigned, it can not be modified | Global or block Scope |
Backtick Strings
Interpolation
let greetings = `Hello ${name}`Multi line Strings
const msg = ` hello world! `Arrays
An array is a collection of items or values.
Syntax:
let arrayName = [value1, value2,..etc]; // or let arrayName = new Array("value1","value2",..etc);Example:
let mobiles = ["iPhone", "Samsung", "Pixel"]; // accessing an array console.log(mobiles[0]); // changing an array element mobiles[3] = "Nokia";Arrow functions
Arrow Functions helps developers to write code in concise way, it’s introduced in ES6.
Arrow functions can be written in multiple ways. Below are couple of ways to use arrow function but it can be written in many other ways as well.
Syntax:
() => expressionExample:
const numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] const squaresOfEvenNumbers = numbers.filter(ele => ele % 2 == 0) .map(ele => ele ** 2); console.log(squaresOfEvenNumbers);De-structuring
Arrays
let [firstName, lastName] = ['Foo', 'Bar']Objects
let {firstName, lastName} = { firstName: 'Foo', lastName: 'Bar' }rest(...) operator
const { title, firstName, lastName, ...rest } = record;Spread(...) operator
//Object spread const post = { ...options, type: "new" } //array spread const users = [ ...adminUsers, ...normalUsers ]Functions
function greetings({ name = 'Foo' } = {}) { //Defaulting name to Foo console.log(`Hello ${name}!`); } greet() // Hello Foo greet({ name: 'Bar' }) // Hi BarLoops
1. If:
IF is used to execute a block of code based on a condition.
Syntax
if(condition){ // code }2. If-Else:
Else part is used to execute the block of code when the condition fails.
Syntax
if(condition){ // code } else { // code }3. Switch:
Switch is used to replace nested If-Else statements.
Syntax
switch(condition){ case 'value1' : //code [break;] case 'value2' : //code [break;] ....... default : //code [break;] }4. For
For loop is used to iterate a set of statements based on a condition.
for(Initialization; Condition; Increment/decrement){ //code }5. While
While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.
while (condition) { // code }6. Do-While
Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.
do { // code } while (condition);Classes
ES6 introduced classes along with OOPS concepts in JS. Class is similar to a function which you can think like kind of template which will get called when ever you initialize class.
