stdlib.io is a data process/vis library, not a standard library.
jQuery was a DOM/Utility DX library (and also a compatibility layer before all browsers finally focussed on standards), not a standard library.
Deno people are trying so fucking hard to be relevant. It’s embarrassing. Bringing nothing to the table has been their MO from day 1.
Let's examine that.
Deno has always been:
(parapharing) "Hi, I'm the creator of Node and want to make it better but can't get everyone on board with the changes. So I'm going to create a new JS runtime. Node will need to implement these improvements to keep up or everyone will switch away from node. Either way, developers win."
We know it's been that way since he was a month into Deno's development in his famous talk: 10 Things I Regret About Node.js
Deno [...] Bringing nothing to the table [...]
Have a look through each of those 10 points he brought up, then compare that to node before, and node now. It's pretty clear he gave them the swift kick in the ass to start making those changes. We win. That's clearly a success.
QOI is just a format that's easy for a programmer to get their head around.
It's not designed for everyday use and hardware optimization like jpeg-xl is.
You're most likely to see QOI in homebrewed game engines.
