Datepicker title should switch to a month picker, then the month picker a year spinner/picker. The pattern was first really codified in the MS Ajax Toolkit, probably the only thing I liked in that framework.
The issue is that someone will use this library, and then use it for something like a date of birth field.
Generally not a fan of "Top N" or "Best N" reviews, and that holds here as well. There's no mention of exactly how these are the top/best.
There are mentions to github/npm stats but not if they are actually the top of either. I do appreciate that the article mentions an option for bare client, react, node, nextjs and angular options. I only wish the method for selection were disclosed.
There's a lot to *really* like about Deno... I know there's a few areas that are a bit more difficult, and a lot of things in Node, with no similar libraries in sight for Deno.
That said, I've played with it a bit, and I like a lot of it. I hope that more libraries and projects become compatible with published releases.
I do think the library framework release system is a bit different and could lead to some interesting innovations. I'm not completely convinced it's that much better than npm, but it definitely feels easier.
It's not really faster for most applications... it can be nice if you're enhancing a mostly static generated site.
Really wish there was a good solution for JSX with ES Modules... you *could* either do any translation server-side, or use some worker solution(s), but it gets messy. Similar for TS.
Have done a couple proof of concept bits, but it can get sticky really quickly.
Probably worth adding to the examples...
typeof undefined === "undefined"
typeof NaN === "number"
NaN in particular, along with Invalid Date can be interresting corner cases in practice. I find it's often best to rely on coercion and input validation over type checking.
The first followup to this should probably be falsey values, and how knowing them is useful for input validation.
Venturing OT, but if you're doing end to end tests, I would suggest getting familiar with Docker, docker-compose and its' usage. It's very easy to stand-up your entire environment, run your tests, and stand-down said environment. Many CI/CD runners have a full docker environment available, so this makes integration super easy as well.
