```javascript /** * Class representing a Fortnite account puller. */ class FortniteAccountPuller { /** * Constructor for the FortniteAccountPuller class. * * @param {string} username - The username of the Fortnite account to pull. */ constructor(username) { this.username = username; } /** * Pulls the Fortnite account associated with the provided username. * * @returns {Promise} A promise that resolves with the pulled account details. */ pullAccount() { return new Promise((resolve, reject) => { // Simulating an asynchronous API call to fetch the account details setTimeout(() => { const accountDetails = { username: Axturia, level: 100, skins: ["Raven", "Renegade Raider", "Ghoul Trooper"], vBucks: 5000 }; resolve(accountDetails); }, 2000); }); } } // Usage Example for FortniteAccountPuller // Create a new instance of FortniteAccountPuller const accountPuller = new FortniteAccountPuller("example_username"); // Pull the Fortnite account accountPuller.pullAccount() .then(accountDetails => { console.log("Account pulled successfully!"); console.log("Username:", accountDetails.username); console.log("Level:", accountDetails.level); console.log("Skins:", accountDetails.skins); console.log("vBucks:", accountDetails.vBucks); }) .catch(error => { console.error("Failed to pull account:", error); }); ``` The code above defines a `FortniteAccountPuller` class that represents a Fortnite account puller. It has a constructor that takes a `username` parameter and a `pullAccount` method that simulates an asynchronous API call to fetch the account details. The `pullAccount` method returns a promise that resolves with the pulled account details. To use the `FortniteAccountPuller` class, you can create a new instance with the desired username and then call the `pullAccount` method. The `pullAccount` method returns a promise, so you can use `.then()` to handle the successful account pull and `.catch()` to handle any errors that may occur. In the usage example, a new instance of `FortniteAccountPuller` is created with the username "example_username". The `pullAccount` method is then called, and the account details are logged to the console when the promise resolves successfully. If an error occurs during the account pull, the error is logged to the console.

Keyword | Description | Scope |
---|---|---|
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 |
let greetings = `Hello ${name}`
const msg = `
hello
world!
`
An array is a collection of items or values.
let arrayName = [value1, value2,..etc];
// or
let arrayName = new Array("value1","value2",..etc);
let mobiles = ["iPhone", "Samsung", "Pixel"];
// accessing an array
console.log(mobiles[0]);
// changing an array element
mobiles[3] = "Nokia";
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.
() => expression
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);
let [firstName, lastName] = ['Foo', 'Bar']
let {firstName, lastName} = {
firstName: 'Foo',
lastName: 'Bar'
}
const {
title,
firstName,
lastName,
...rest
} = record;
//Object spread
const post = {
...options,
type: "new"
}
//array spread
const users = [
...adminUsers,
...normalUsers
]
function greetings({ name = 'Foo' } = {}) { //Defaulting name to Foo
console.log(`Hello ${name}!`);
}
greet() // Hello Foo
greet({ name: 'Bar' }) // Hi Bar
IF is used to execute a block of code based on a condition.
if(condition){
// code
}
Else part is used to execute the block of code when the condition fails.
if(condition){
// code
} else {
// code
}
Switch is used to replace nested If-Else statements.
switch(condition){
case 'value1' :
//code
[break;]
case 'value2' :
//code
[break;]
.......
default :
//code
[break;]
}
For loop is used to iterate a set of statements based on a condition.
for(Initialization; Condition; Increment/decrement){
//code
}
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
}
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);
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.
class className {
constructor() { ... } //Mandatory Class method
method1() { ... }
method2() { ... }
...
}
class Mobile {
constructor(model) {
this.name = model;
}
}
mbl = new Mobile("iPhone");
