This example demonstrates a terminal-based progress bar that tracks task completion with live performance metrics. The bar displays current and total counts, elapsed time, estimated time remaining, throughput in ticks per second, and memory usage. It builds on the `ora` spinner, `chalk` for colored output, and `pretty-ms` for human-readable time formatting. The bar updates by mutating the spinner’s text property, appending status lines, and uses `process.hrtime` for precise timing and `process.memoryUsage` for heap data.
