// Define our todo list
let toDoList = [];
// Function to add items to todo list
const addItem = item => {
toDoList.push(item);
console.log(`You added "${item}" to the to do list.`);
}
// Test todo list
addItem('Buy milk');
addItem('Buy eggs');
addItem('Clean the house');
// Function to remove an item
const removeItem = item => {
const searchIndex = toDoList.indexOf(item);
if (searchIndex !== -1) {
toDoList.splice(searchIndex, 1);
} else {
console.log('Item not found.');

// JavaScript code to create a ToDo List

}
// Function to remove todo by index from the list

//This is a very basic todo list, here is the code for it:
//Array to store todo list items
const todoList = [];
//Function to add todo items
function addTodo(todoText) {
todoList.push({
todoText: todoText,
completed: false
});
};
//Function to delete todo items
function deleteTodo(position) {
todoList.splice(position, 1);
};
//Function to change todo items
function changeTodo(position, todoText) {
todoList[position].todoText = todoText;
};
//Function to toggle todo items
function toggleTodo(position) {
const todo = todoList[position];
todo.completed = !todo.completed;
};

// Set up an array to store task items
let todoList = [];
// Create a function to add new task items to the list
function addTask(task) {
if (task) {
todoList.push(task);
console.log("Task added: " + task);
} else {
console.log("You must enter a task to add!");
}
}
// Create a function to remove an item from the list
function removeTask(task) {
let index = todoList.indexOf(task);
if (index !== -1) {
todoList.splice(index, 1);
console.log("Task removed: " + task);
} else {
console.log("Task not found");
}
}
// Create a function to list all tasks in the list
function listTasks() {
console.log("*** TODO List ***");
todoList.forEach(function(task) {
console.log(task);
});
}
// Test the functions
