Bash is great, but when it comes to writing more complex scripts, many people prefer a more convenient programming language. JavaScript is a perfect choice, but the Node.js standard library requires additional hassle before using. The zx package provides useful wrappers around child_process, escapes arguments and gives sensible defaults.
