Actually, I use Nim at work. I'd used Nim at work for processing a couple of large Excel files (more to come) and ingesting the processed data into a Postgres database.
I initially planned on using Go, but for some reason, Go was not that fast in reading the large file (117 MB -> 0.5 million rows) and printing it on the console (for me to inspect). I tried using a goroutine, but it was getting killed. I didn't have time to debug and fix it. So, I looked to Nim (my fav programming language btw). I even considered C++, but the only good and free (free as in free beer) library is not maintained promptly. So, I ditched that. And I finally used Nim. And it was a breeze to use. I'm pretty sure that Nim will find itself being used in data processing a lot. All the necessary utility functions are already available in the standard library and if you want to write a couple yourself, it's very easy. I had also convinced my CTO to use Nim to write a REST API over our database (I have paused that task for now). I'm using Prologue (which also comes with built-in support for OpenAPI (aka Swagger) docs. I would love to continue using Nim in my org (there are some data pipelines to be built). And for everything and anything (of course!). I'm also looking forward to learn data structures and algorithms, and computer architecture and organisation, and compilers using Nim.
