Summary

The classic first JS project — add, complete, delete and filter tasks — practicing DOM manipulation, events, arrays and localStorage persistence together. This project combines state, events, DOM updates, persistence, filtering, and user interaction, making it a strong exercise for connecting multiple beginner JavaScript concepts.

• 1Persist tasks to localStorage so they survive a page refresh. Validate your understanding by applying it in a small practical example.
• 2Add filtering (all/active/completed) using array `.filter()`. Test the result on both a successful path and an invalid or unexpected input.
• 3Practice event delegation for delete buttons on dynamically added items.
