// Here is task one:

// Todo List App

// Goal: Simple to-do app with in-memory task storage.
// Each task should have an: id, title, completed

// Features:

// Add task
// Mark task as done/undone
// Filter task according to:  completed | pending tasks
// Delete task

// const Task = {
//     id: 0,
//     title: "",
