The Final Project Using Modern JavaScript Features combines ES6, ES2020, ES2022, asynchronous programming, modules, collections, classes, APIs, and modern syntax to build a real-world scalable JavaScript application. Understanding the Final Project Using Modern JavaScript Features helps beginners apply advanced JavaScript concepts practically and become industry-ready frontend developers.

<!DOCTYPE html>
<html>
<head>
<title>Task Manager</title>

<body>
<h1>Task Manager</h1>
<input type="text" id="taskInput">
<button id="addBtn">Add Task</button>
<ul id="taskList"></ul>
<script type="module" src="app.js"></script>
</body>
</html>The application contains:
export class TaskManager{
#tasks = [];
constructor(){
this.loadTasks();
}
addTask(task){
this.#tasks.push({
id: Date.now(),
task,
completed: false
});
this.saveTasks();
}
getTasks(){
return this.#tasks;
}
completeTask(id){
let task = this.#tasks.find(t => t.id === id);
task?.completed = true;
this.saveTasks();
}
deleteTask(id){
this.#tasks = this.#tasks.filter(t => t.id !== id);
this.saveTasks();
}
saveTasks(){
localStorage.setItem(
"tasks",
JSON.stringify(this.#tasks)
);
}
loadTasks(){
this.#tasks = JSON.parse(
localStorage.getItem("tasks")
) ?? [];
}
}Concepts used:
import { TaskManager } from "./taskManager.js";
const manager = new TaskManager();
const input = document.getElementById("taskInput");
const button = document.getElementById("addBtn");
const list = document.getElementById("taskList");
function render(){
list.innerHTML = "";
manager.getTasks().forEach(task => {
const li = document.createElement("li");
li.innerHTML = `
${task.task}
<button data-id="${task.id}">
Delete
</button>
`;
if(task.completed){
li.style.textDecoration = "line-through";
}
list.appendChild(li);
});
}
button.addEventListener("click", () => {
if(input.value.trim()){
manager.addTask(input.value);
input.value = "";
render();
}
});
list.addEventListener("click", event => {
const id = Number(
event.target.dataset.id
);
if(id){
manager.deleteTask(id);
render();
}
});
render();Concepts used:
Dynamic Import loads:
export function showMessage(){
console.log("Utility Loaded");
}async function loadUtils(){
const module = await import("./utils.js");
module.showMessage();
}
loadUtils();Concepts used:
Example:
const categories = new Set();
categories.add("Work");
categories.add("Personal");
console.log(categories);Sets manage:
Example:
const metadata = new Map();
metadata.set("theme", "dark");
metadata.set("version", "1.0");
console.log(metadata.get("theme"));Maps manage:
export async function getUsers(){
const response = await fetch(
"https://jsonplaceholder.typicode.com/users"
);
return await response.json();
}import { getUsers } from "./api.js";
const users = await getUsers();
console.log(users);Concepts used:
Example:
console.log(user.profile?.name);This prevents:
Example:
const username = user.name ?? "Guest";This provides:
Example:
const proxy = new Proxy({}, {
set(target, property, value){
if(value === ""){
throw new Error("Empty Value");
}
target[property] = value;
return true;
}
});Concepts used:
| Feature | Usage |
