The document announces a Smalltalk meetup happening on November 10th 2023 that will feature a talk about PharoJS, a framework that allows developers to write code in Pharo and run it on JavaScript. PharoJS provides a transpiler to convert Pharo code to JavaScript, libraries to extend JavaScript objects with Pharo behaviors, and tools like a playground and inspector for JavaScript objects. Examples of projects using PharoJS include mobile apps built with HTML/CSS and web apps like PLC3000.com which has over 1000 tests and classes for its client and server code.
