Is It JavaScript?

Sprig is a tile based game engine made by Hack Club that&#x27;s like Scratch&#x27;s older brother but has it&#x27;s own set of unique limitations.All sprites need to be made in Bitmap and uses a midi like event sequencer to get any music into it, since it&#x27;s meant for a different set of hardware, you can only use very basic controls too.I made a version of PacMan inside it that has randomly generated mazes every time and mostly works well!

No-JavaScript Fingerprinting

There’s much prior art (good overview here: https:&#x2F;&#x2F;sr.ht&#x2F;~bptato&#x2F;chawan&#x2F;#neighbors), but I’m doing something different that wants to exist.Curious as to response. Probably a few weeks off release yet but here’s a brief screencap: https:&#x2F;&#x2F;youtu.be&#x2F;_Bs7BoQBoBA (Or if you prefer an asciinema: https:&#x2F;&#x2F;asciinema.org&#x2F;a&#x2F;9w6CMnaI9VxiykI1PgVWm4lsi )Thoughts?The context is it’s meant for constrained environments (ultra thin client, engine runs remotely or on same machine if you like; security constraints? Bandwidth constraints? Resource constraints? Content constraints?).Personally, this is a project close to my heart because my first interactions with computers, and even the Internet was textbased back in the days of dialup and BBS systems. But for another reason in the modern era, I often have the feeling I just wanna get away from all the bullshit all the colors and images begging for my attention. I just want a quiet web that works. But I don’t like an extension knowing everything, and content scripts are fragile. For me, the medium of the terminal is actually a different message and distinct experience that I find valuable. And I think the Internet wants to see itself that way too.So I’m building this whatever the response here. I also think maybe I can make a trendy thing as OCR is still a major problem and if AI’s can have a text based way to drive web content, maybe they’d like that. Not my main bag though, but I need to consider cash.I have some other fun ideas for this too, that’s a real nod to the past; a more civilized age.

JavaScript Obfuscation Through File Stream Side-Channel

Hi HN,We’re Shreyash and Bhavnick. We built Chonkie, an open-source library for advanced chunking and embedding of text and code. It was previously Python-only, but we just released a TypeScript version: <a href="https:&#x2F;&#x2F;github.com&#x2F;chonkie-inc&#x2F;chonkie-ts">https:&#x2F;&#x2F;github.com&#x2F;chonkie-inc&#x2F;chonkie-ts</a>Many AI projects in JS&#x2F;TS (like those using Vercel&#x27;s AI SDK or Mastra) rely on basic text splitters. But better chunking = better retrieval = better performance. That’s what Chonkie is built for.Current native chunkers (in TS):- Code Chunker – handles Python, TypeScript, etc.- Recursive Chunker – rule-based, hierarchical splitting- Token Chunker – split by token count (fully customizable)- Sentence Chunker – split on sentence boundaries. Delimiters are customizable, so it works for multiple languages.All chunkers support custom tokenizers, chunk overlap, delimiters, and more.Coming soon in native TS (already available via the API client):- Semantic Chunker – splits texts wherever it detects a shift in meaning.- SDPM Chunker – merges semantically similar disjoint chunks- Late Chunker – generates context-aware embeddings for each chunk- Slumber Chunker – LLM-refined recursive chunks. Significantly reduces token usage (and thus cost) while maximizing chunk quality.- Embeddings Refinery - Embed chunks with any embedding model- Overlap Refinery – Create overlaps between consecutive chunks for better context preservation.Chonkie is free, open-source, and MIT licensed. GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;chonkie-inc&#x2F;chonkie-ts">https:&#x2F;&#x2F;github.com&#x2F;chonkie-inc&#x2F;chonkie-ts</a>We’d love your feedback, ideas, or contributions. Thanks!

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]);
 }
 }
```
