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. No compromise, take the best of both. The zx package provides useful cross-platform wrappers around child_process, escapes arguments and gives sensible defaults.
