Sure, the the node code uses fewer lines than the Go code. But what you’ve failed to notice is the Go code calls APIs directly rather than fork()ing and does so within its own code base (how many lines of code is in the countless imports of your node example?). Plus the Go code also has unit tests which the others don’t.

Line numbers are always a terrible metric for proving anything but in this case your especially abusing that data.

In absence of more accessible complexity measurements, line counts do matter somewhat. E.g. the briefer a program is, the more readable it is (last time I checked, brainpower and time is much more expensive than computing power and bandwidth.)

The Node example has zero external dependencies outside of the Node.js standard library.

Well, compared to a shell script or a static binary...the Node example requires you to have Node (+ NPM) on your machine and, unless you wrap it all up for homebrew/apt/some other package repo. you're going to be using `npm install -g` to use it as opposed to shoving an executable into your PATH.

All of your stated benefits are nice for the maintainer but mean little to the end user. This gushing praise for Node reads like nobody has ever built elegant CLI apps until Ryan Dahl turned of age and put JS on a server.

There are as many exceptions to that rule are there are examples when it’s true. Code golfing, minifified code, shell 1 liners, Perl, etc.

Line counts mean jack shit.

I would argue that even an esoteric, densely packed one-liner can still be more readable than the equivalent program spread out over a greater number of lines - simply because you can keep it all in sight at the same time and work through it without losing the bigger picture.

But of course, scary symbols is scary.

So you'd like to use APL, then? He didn't say symbols. Verbose code can be much easier, though stupidly verbose is stupid. Compromise is, as usual, the best solution.
