📝What makes Smalltalk extensible?

§ Extensible system Smalltalk
  • Inspectable. You can expect any object in the system. You can look them up, sort, and search.
  • Self-contained. Most of the Smalltalk is implemented in Smalltalk. This allows looking at and changing any part of the system.
  • Simple universal metaphor. In Smalltalk everything is an object, and you can send a message to any object.
  • Dynamic, runs on VM. You don’t have to wait for the whole system to recompile when you introduce a change.
