And here is the same thing in Deno: https://gist.github.com/zandaqo/93004fb265146a95aadb28ec851a...

That doesn't quote/escape arguments and with zx you can do the shebang so you don't need the import but implementing that in deno shouldn't be too hard I think.

Zx is good if JavaScript is only language you know. If you have ability to program or learn other programming languages, Python with packages like Shell and Plumbum might be better choices for shell scripting tasks that outgrow shell. - Python code with Shell is easier to read ana write - No nees to carry async/await keywords thru the code - Powerful plain text manipulation in the stdlib https://pypi.org/project/pyth…

> Python code with Shell is easier to read and write

That is pretty subjective

Maybe but Python is sloooow and its type annotation situation is pretty poor.

I would recommend using Deno. It has the following advantages:

* Uses Typescript which gives you a great static typing system.

* Runs via V8 so it's about a million times faster than Python.

* Single statically linked binary with no project setup files required (package.json/dependencies.txt) makes it about a million times easier to deploy than either Node or Python. Especially on Windows.

* You can still use third party libraries even without a project file and you get IDE integration.

It's the clear winner at this point. Someone has even made a version of zx for it:

I feel like the await keyword everywhere is a bit verbose. One might use something like the gpp preprocessor (hopefully the macros could be defined in a separate file):

        #!/usr/bin/env zx

        #define _ await $
        #define __ await Promise.all

        #define _1 process.argv[1]
        #define _2 process.argv[1]
        #define _3 process.argv[1]

        _`cat package.json | grep name`

        let branch = _`git branch --show-current`
        _`dep deploy --branch=${branch}`

        __([
          $`sleep 1; echo 1`,
          $`sleep 2; echo 2`,
          $`sleep 3; echo 3`,
        ])

        let name = 'foo bar'
        _`mkdir /tmp/${_1}`

Ugh, typing `await` for every command is terrible. JavaScript's async-by-default model is clearly not a good fit for this use case.

Maybe, but the main advantage of `zx` (at least for me) is that I don't have to manage another language environment. I can keep everything contained within Node :)

What is there to manage? Python comes built-in with pretty much every distro, and you only have to install one package.

I’ve found Python is just fine performance-wise for CLI tools. What bad experiences have you had with it? I’ve mostly used click.

I don't think it is very relevant to critique the Javascript syntax on a post about a specific library
