Speed of iteration is for speed of feedback and insight from the business/market into the product.
That can be a mix of how you see it, how the business works and how the code does anything.
It is important to understand I’m not referring to dynamically vs statically typed languages or not. It’s a distraction. Code runs fast on pretty much anything these days, and dynamically typed languages have pre-compilers.
These are sometimes matters of personal experience, interpretation, preference and opinion masquerading as facts.
Most languages have to abstract from to the web using a framework and that additional interpretation is where a lot is lost.
Featuritis is the disease, solving problems solely based on customer input (who are strangers) is important. Problems are rarely a single feature, but a sequence or group of them.
The irony of bash scripts is they can be some of the most durable and well lasting parts of a project while everything around it might change and evolve quicker. So if there’s some bash scripts being called by a language in the beginning.. so what.
My original point about Laravel is I have not seen as tightly integrated of any ecosystem to ship solutions and product where so much time is not lost in the product side of it (accounts, billing, migrations, etc). While I’m relatively new to it, at the very least it’s a worth comparison to show the holes in others.
