Secure coding in #JavaScript, my latest blog on #stackoverflow JavaScript is the front-end of the entire internet. Because JavaScript is so prolific, it’s a prime target for attackers.
Been updating my personal Mastodon tooling to download and convert my bookmarked toots. Here's how little code is needed to download a single message and convert its HTML content into Markdown, all using these #ThingUmbrella packages:
- https://thi.ng/hiccup: Interop data format (i.e. just nested JS arrays) to encode hierarchical documents
- https://thi.ng/hiccup-html-parse: Parses HTML into hiccup format
- https://thi.ng/hiccup-markdown: Serialize hiccup to Markdown (also includes a Markdown parser to hiccup, but not used here)
- https://thi.ng/zipper: Functional tree editing, manipulation & navigation (here to clean/transform the parsed HTML document)
Edit: Gist version of this example code:

Note to Web builders: One of the tiny things I did while wiring Pagefind into the blog was arrange, when you pop open the search field, that that the input has focus so you can start typing. There are plenty of sites I visit where the obvious thing you want to do is type into a search field, but you have to click first, which is just wrong. It’s not hard with basic JavaScript and you don’t need jQuery or anything.
How to build a key-value database from scratch (with JavaScript code)

Hey hive mind - I'm keen to start a PhD and move toward academia, and am thinking about potential research topics. I'm an experienced structural #engineer and want to transition toward #sustainability as much as I can. But I'm not sure what that means for viable #research areas...
I have particular expertise in mechanics of #materials, software development ( #Python and #JavaScript), and cold-formed steel / #buckling of thin-walled structures.
Anyone out there have any suggestions for specific topics or general directions?

To create the map, I adapted a browser-based #JavaScript app that I coded back in February: https://en.osm.town/@seav/113963871173548456
Using the #MediaWiki API, the app extracts destination airports from Changi’s #Wikipedia article, then queries the coordinates and IATA code of those airports from #Wikidata. The app finally renders an initial SVG image using #NaturalEarth as the world base map.
I then used #Inkscape to manually adjust labels to avoid overlaps and then #GIMP for final touches.

I’m experimenting generating airport route maps where I take the passenger destinations served by an airport from the airport’s #Wikipedia article, extract the coordinates from #Wikidata, and then render them on a custom logarithmic azimuthal map.

I didn’t know either of my Nans very well.
As individuals Nan !== Nan.
But to the best of my knowledge they were both NaN

PiccalilliNaN, the not-a-number number that isn’t NaNWe're pretty aware, generally that JavaScript is weird, but did you know Not-A-Number (NaN) is a type of number? Mat Marquis walks us through why that is and how to deal with NaN well in your codebases.
Announcing Duper: The format that's super!
An MIT-licensed human-friendly extension of #json with quality-of-life improvements (comments, trailing commas, unquoted keys), extra types (tuples, bytes, raw strings), and semantic identifiers (think type annotations).
Converting to and from Base64 in #JavaScript:
> Uint8Array.of(0, 1, 2).toBase64()
'AAEC'
> Uint8Array.fromBase64('AAEC')
Uint8Array.of(0, 1, 2)

Community work in the Swift for Wasm ecosystem has gained momentum and deserves regular status updates at this point. Here's what we've achieved just in the last few months: https://forums.swift.org/t/swift-for-wasm-september-october-2025-updates/82966
Swift Forums · Swift for Wasm September-October 2025 UpdatesI'm excited to share an update on the latest progress in the Swift for WebAssembly ecosystem! Last two months of community's work were mainly focused on polishing the Swift toolchain, developing new features in our primary packages (namely JavaScriptKit and WasmKit), while also porting existing Swift libraries to Wasm. Here’s a list of notable changes prepared with help from @kateinoigakukun, @krodak, and @scottm: Swift Toolchain Fixed SwiftPM passing incorrect CLI arguments to WasmKit when r...
NEW! Fastly's HTML Rewriter is live in the JS SDK (v3.35.0) for Compute.
It's a native, streaming parser that lets you modify HTML at the edge with CSS selectors—and it's ~20x faster than old-school DOM buffering.
Say goodbye to origin strain. Say hello to instant personalization.

gomakethings.comJust use HTMLI’ve worked on so many projects recently that were more complicated than they needed to be because they used JavaScript to generate HTML.
JavaScript is… Slower to load Slower to run More prone to breaking Harder to read and reason about Doesn’t actually look like the final output It’s inferior to just using HTML in nearly every way.
I’m not saying never use JavaScript, though. I think JS is great at augmenting and enhancing what’s already there, and adding interactivity that cannot (yet) but handled with HTML.
Anyone aware of #Javascript jobs at a not evil/impactful company?
I’ve got 15 years of experience, fluent in React and NodeJS with Express. Experience with Postgres, SQLite and NoSQL databases. Got my last company Cyber Essentials Certified. Im proficient in dev ops and sys admin. Have a small (but growing!) portfolio of FOSS work.
Have an extensive background in teaching programming too, so can mentor juniors. I LOVE mentoring. Have an academic background too. #GetFediHired boosts welcome
