For our December meeting, Florin Mateoc will show us JsSqueak , a JavaScript implementation of (JavaScript compiled) Squeak. Whereas SqueakJS or TruffleSqueak are implementations of the Squeak stack VM which run the Squeak bytecodes, JsSqueak compiles all the Squeak code to JavaScript (including the VM plugins), it exports the image state as one big JavaScript storeString, and then loads them, and runs the JavaScript implemented minimal VM (mostly primitives) and the JavaScript-translated Squeak methods as one combined JavaScript application. The compiled JavaScript application can be run either in a browser or in Node.js While JavaScript, especially with its newest additions, is a very powerful language, which allows us to implement most Smalltalk-specific features (e.g. processes/green threads are implemented using generator functions and recursive yield* for all invocations, DNU is implemented using proxies and proto manipulation, the Smalltalk parallel class hierarchy is implemente
