It's kinda wild that #JavaScript has *three* different representations for “no value”:
* null: This means there isn't a value here in this instance, but there could have been.
* undefined, and the property doesn't exist: This means there isn't a value here and probably never could have been.
* undefined, but the property does exist: 🤷♂️

I did better on this one. I know more about #email than I know about #JavaScript.
They tease me that this is also the score you get if you just answer valid to every question. But I came by it honestly.
I scored 14/21 on https://e-mail.wtf and all I got was this lousy text to share on social media.

Any TypeScript experts know how to make the language immutable by default? I got it working for Array and Record, but not plain objects... https://evanhahn.com/typescript-immutability-experiment/
Love it when a near complete project just appears out of nowhere.

I’ve seen one-time passcode (“OTP”) interfaces cause undue stress in otherwise level-headed #WebDev teams.
Thankfully, it doesn’t have to be complicated: https://cloudfour.com/thinks/simple-one-time-passcode-inputs/
I feel like I heard about some new framework that yt-dlp is using to render JavaScript that isn't a full ass chromium instance; anyone remember what I'm talking about?
Interest: rendering HTML for (polite, non genAI) scraping purposes (think personal storage for semi-archival, note keeping, etc, purposes) and calling it via Python

"There is no syntactic means to create instances of GeneratorFunction subclasses" says the ECMAScript specification. Well, if you just call your new constructor it works fine ¯\_(ツ)_/¯
