File Download Progress Tracker

Build a command-line utility that simulates downloading files and displays real-time progress feedback to the user.

Requirements

The utility should:

1. Accept a list of file names and their sizes (in MB) as command-line arguments
2. Simulate downloading each file sequentially by waiting an appropriate amount of time
3. Display a visual progress indicator that updates as each file downloads
4. Show percentage completion for the overall download process
5. Print a completion message when all files are downloaded

The progress display should update smoothly during downloads and show clear visual feedback to users about download progress.

API

/**
 * Simulates downloading files with progress display
 * @param {Array<{name: string, size: number}>} files - Array of files with name and size in MB
 */
function downloadFiles(files);

module.exports = { downloadFiles };

Test Cases

• Given an empty file list [], it completes immediately without errors @test
• Given a single file [{name: 'image.jpg', size: 5}], it shows progress from 0% to 100% @test
