👀 Fuse.js 7.3: Lightweight Fuzzy-Search Want a search feature tolerant to ambiguous input without a dedicated backend? v7.3 adds per-term fuzzy matching and a static method for single string matching, while v7.4 beta adds worker-based distributed search for tackling huge datasets. A demo shows off the basics. Kiro Risk

✌️ JSIR: A High-Level IR for JavaScript from Google Google has open sourced a new tool (JSIR) and proposed an industry-standard IR (Intermediate Representation – if an AST tells you what the code looks like, an IR tells you what it does) for JavaScript. Already used at Google for analysis and code transformation, the underlying idea could form a foundation for a new generation of tooling. Zhixun Tan (Google)

🤔 axios Package Compromised; Malicious Versions Added a Trojan Dependency Axios is an HTTP library that gets 100M+ downloads a week, largely due to its legacy popularity. An attacker took advantage of that to roll out a version with a malicious dependency including a remote access trojan (though Axios' codebase itself was fine). This is big, as even if you don’t use Axios, your dependencies might. Here's how to see if you're affected. Ashish Kurmi
