• Add new tasks with a title.
• List all tasks with their status (completed or not).
• Mark tasks as completed.
• Delete tasks.

Prerequisites

• Go installed on your system (version 1.16 or later).

File Structure

• tasks.json: The application stores task data in a tasks.json file in the current directory. If the file does not exist, it will be created automatically.

Error Handling

• If an invalid task ID is provided for complete or delete commands, the application will notify you that the task was not found.
• If no tasks are present, the list command will notify you accordingly.
