Pharo VM Runs Smalltalk in Browser

This is a compelling zero-install showcase for live programming, though browser sandbox limits keep it closer to an experimental runtime and teaching tool than a native VM replacement.

• –Runs actual Pharo images rather than transpiling Smalltalk into JavaScript.
• –Web Workers and canvas keep the browser responsive while the VM executes.
• –Browser restrictions limit native FFI, filesystem access, networking, and integrations such as Git.
• –Makes Pharo dramatically easier to try, teach, embed, and demo.
• –Complements projects like PharoJS by preserving VM-level behavior instead of compiling applications to JavaScript.
