We needed a JS-first WYSIWYG DOCX editor and couldn&#x27;t find a solid OSS option, most were either commercial or abandoned.As an experiment, we gave Claude Code the OOXML spec, a concrete editor architecture, and a Playwright-based test suite. The agent iterated in a (Ralph) loop over a few nights and produced a working editor from scratch.Core text editing works today. Tables and images are functional but still incomplete. MIT licensed.

QuickBEAM is a JavaScript runtime embedded inside the Erlang&#x2F;OTP VM.If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code.QuickBEAM runs that JavaScript inside OTP supervision trees.Each runtime is a process with a `Beam` global that can:
- call Elixir code
- send&#x2F;receive messages
- spawn and monitor processes
- inspect runtime&#x2F;system stateIt also provides browser-style APIs backed by OTP&#x2F;native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.).This makes it usable for:
- SSR
- sandboxed user code
- per-connection state
- backend JS with direct OTP interopNotable bits:- JS runtimes are supervised and restartable
- sandboxing with memory&#x2F;reduction limits and API control
- native DOM that Erlang can read directly (no string rendering step)
- no JSON boundary between JS and Erlang
- built-in TypeScript, npm support, and native addonsQuickBEAM is part of Elixir Volt — a full-stack frontend toolchain built on Erlang&#x2F;OTP with no Node.js.Still early, feedback welcome.

Creator here. Hologram compiles Elixir to JavaScript to run in the browser, enabling full-stack development in pure Elixir - and soon, Local-First applications.This release is a milestone for our porting initiative. 49 contributors ported 150 Erlang functions across 19 modules, pushing client-side Erlang runtime coverage from 34% to 96% and overall Elixir standard library readiness from 74% to 87%.This means the vast majority of Elixir standard library functions needed for full-stack web and basic local-first apps now work in the browser - string processing, collections, sets, binary operations, Unicode normalization, math, time operations, file path handling, and more.Beyond porting, the release includes enhancements, bug fixes, and infrastructure groundwork.Happy to answer any questions!

Wrote a thing about what makes Elysia stand out in a performance benchmark gameBasically, there&#x27;s a JIT &quot;compiler&quot; embedded into a frameworkThis approach has been used by ajv and TypeBox before for input validation, making it faster than other competitorsElysia basically does the same, but scales that into a full backend frameworkThis gave Elysia an unfair advantage in the performance game, making Elysia the fastest framework on Bun runtime, but also faster than most on Node, Deno, and Cloudflare Worker as well, when using the same underlying HTTP adapterThere is an escape hatch if necessary, but for the past 3 years, there have been no critical reports about the JIT &quot;compiler&quot;What do you think?

Hi HN!I&#x27;ve been building this solo for about three and a half years. I kept trying every new project&#x2F;notes tool (Notion, Asana, Trello, etc.) and always ended up back in a plain text file. I wanted something that felt like a text editor on first touch but could grow into real structure when you needed it.<a href="https:&#x2F;&#x2F;lightwave.so" rel="nofollow">https:&#x2F;&#x2F;lightwave.so</a> (desktop only)The tech stack is Laravel, MySQL, Redis, and hand-rolled JavaScript on the client. No frameworks like React&#x2F;Vue&#x2F;etc. ~270 lines of jQuery (out of 80k+ total LOC) for a few legacy DOM utilities, plus IndexedDB for local persistence. Real-time collaboration uses a hybrid approach: HTTP&#x2F;2 POST for resilient ops + WebSockets via Laravel Reverb for live cursors, presence, and edits.This is a pre-release stress test, not a launch. Lightwave will be a paid product. Right now I&#x27;m opening it up because no amount of solo testing replicates getting punched in the mouth by real traffic.The link above has a button to create a test account in 1 click.Known rough edges: the cursor and selection system are built from scratch (like VS Code, not a contenteditable wrapper), so there&#x27;s a lot of surface area. Some keyboard shortcuts may be missing. Desktop only, accessibility not yet implemented. I&#x27;m shipping fixes in real time.There&#x27;s a &quot;Submit Bug or Feedback&quot; button inside the app if something breaks. Happy to answer any questions about the architecture, or anything else.Some highlights:- Paste markdown in, get native blocks. Copy blocks out, get markdown back.- Hierarchical document, structure. Hierarchichal file manager.- Live collab with shared cursors, selection, and presence.- Code blocks with syntax highlighting. LaTeX math blocks.- Full data export: markdown, JSON, and attachments. No lock-in.- Full undo&#x2F;redo with cursor restoration.

JavaScript powers the web - it's **the** most important programming language you need to know as a web developer.

## Exempel 1

For example, We have an array of different objects that can weigh the same or different and are spaced apart from us.
The customer wants the lightest and closest object.

```js
object.sort((a,b)=>a.weigh - b.weigh)

 const lightest=(object[0].weigh);
 let sortDistance=(object[0].distance); 

 for (let i = 0; i< object.length; i++) { 
 if (lightest === object[i].weigh && sortDistance > object[i].distance){
 sortDistance = object[i].distance;
 sortObject.unshift(object[i]);
 }else{
 sortObject.push(object[i]);
 }
 }
```
