That is one of the potential use cases behind fdir. I am actively using it for a testing framework (private).

The main methodology was benchmarking every little line of code. Since JS has many alternatives for every thing, I had to benchmark a lot of code.

No special tools were used. The performance gains are mostly from not using recursion, less function calls etc. It could further be optimized of course (and I am working on that).

Thanks for taking the interest :)

Do you mind sharing how you did the benchmarking? console.time, inspector?

I used `benny`. If you have a NodeJS setup you can easily run the benchmarks by:

  npm install

And then:

  node benchmark.js

That will start the asynchronous and synchronous benchmark sequentially.

Thanks for taking the interest.

Edit: benny uses the Benchmark.js library underneath.
