Node Debugger demo
/*
Simple demo to show how the node inspector works
✨ 1: Run with:
node --inspect-brk debuggerdemo.js
By default, the debug process runs on "ws://127.0.0.1:9229", but you can change the port. See node --help for more info
--inspect[=[host:]port] activate inspector on host:port (default: 127.0.0.1:9229)
--inspect-brk[=[host:]port] activate inspector on host:port and break at start of user script

borestad / bash argument parsing.md
Created September 20, 2023 08:32
This code snippet processes command line arguments and assigns values to variables based on the provided options. It supports options like -o (for output), -ttl (for time to live), and their corresponding long forms (--output, --ttl). It also handles

bash argument parsing

Preview:
URL=$1
shift 1

while [ "$#" -gt 0 ]; do
  case "$1" in
    -o) OUTPUT="$2"; shift 2;;
    -ttl) TTL="$2"; shift 2;;
