📝 Issue Reference

Fixes: #3

✅ What Changed

Added validation to prevent adding empty todo tasks.

Now, clicking the Add button with an empty input gives an alert.

Tried adding empty tasks → Not added ✅

Added valid tasks → Works as expected ✅

Current alert messgae: "Please enter a task before adding!"

Alert message seems to lack clarity

The message should be like "Task field is empty"

Thanks for the suggestion 🙌
Instead of using an alert(), I updated the implementation to display the message inside a para element above the input.

New message shown:
Task field is empty ✅

Here’s the updated screenshot after the fix:
