JavaScript (script.js):

document.addEventListener('DOMContentLoaded', () => {

    const taskInput = document.getElementById('task-input');
    const taskList = document.getElementById('task-list');

        li.innerText = taskText;

        const deleteButton = document.createElement('button');
        deleteButton.innerText = 'Delete';

        const toggleCompleteButton = document.createElement('button');
        toggleCompleteButton.innerText = 'Complete';

        return li;

    function saveTask(taskText) {
        let tasks = getTasksFromLocalStorage();
        tasks.push({ text: taskText, completed: false });
        localStorage.setItem('tasks', JSON.stringify(tasks));

    function deleteTask(taskText) {
        let tasks = getTasksFromLocalStorage();
        tasks = tasks.filter(task => task.text !== taskText);
        localStorage.setItem('tasks', JSON.stringify(tasks));

    function updateTaskStatus(taskText) {
        let tasks = getTasksFromLocalStorage();
        tasks = => {
            if (task.text === taskText) {
                task.completed = !task.completed;
            return task;
        localStorage.setItem('tasks', JSON.stringify(tasks));

    function getTasksFromLocalStorage() {
        const tasks = localStorage.getItem('tasks');
        return tasks ? JSON.parse(tasks) : [];

    function loadTasks() {
        const tasks = getTasksFromLocalStorage();
        tasks.forEach(task => {
            const taskItem = createTaskElement(task.text);
            if (task.completed) {


These projects will help you gain practical experience with JavaScript, including DOM manipulation, API integration, state management, and more. Each project provides opportunities to learn and apply different aspects of JavaScript and web development. Start with simpler projects like the To-Do List Application and gradually move on to more complex ones like the Chat Application or Weather App.
