✌️ 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)

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
