Merge 295fe153ad into 2922bbdd6a

Hello, I've added a small blockquote below the description to indicate that this method of accessing an indefinite number of function arguments has been superseded by the use of the spread operator via rest parameters for ES6+ compatibility.

+# Check Network Quality Stats From The Command Line
+
+MacOS comes with a little known CLI utility for checking your current network
+quality statistics. It is aptly named `networkQuality`.
+
+Here is what a basic run of the tool might output:
+
+```bash
+$ networkQuality
+
+...
+Downlink: capacity 281.430 Mbps, responsiveness 101 RPM - Uplink: capacity 16.629 Mbps, responsiveness 101 R
+Downlink: capacity 285.534 Mbps, responsiveness 101 RPM - Uplink: capacity 16.028 Mbps, responsiveness 101 R
+==== SUMMARY ====
+Uplink capacity: 22.982 Mbps
+Downlink capacity: 288.152 Mbps
+Responsiveness: Low (93 RPM)
+Idle Latency: 26.375 milliseconds
+```
+
+You can get an even more detailed summary with the `-v` option:
+
+```bash
+$ networkQuality -v
+
+...
+==== SUMMARY ====
+Uplink capacity: 18.257 Mbps (Accuracy: High)
+Downlink capacity: 469.355 Mbps (Accuracy: High)
+Responsiveness: Medium (252 RPM) (Accuracy: High)
+Idle Latency: 25.583 milliseconds (Accuracy: High)
+Interface: en0
+Uplink bytes transferred: 19.750 MB
+Downlink bytes transferred: 488.265 MB
+Uplink Flow count: 8
+Downlink Flow count: 12
+Start: 9/24/24, 11:06:20 AM
+End: 9/24/24, 11:06:30 AM
+OS Version: Version 13.5.2 (Build 22G91)
+```
+
+See `man networkQuality` for more details.
