SmallTalk

What is SmallTalk?

• Smalltalk is an pure object-oriented, dynamically typed, reflective programming language.
• In this every thing is an object .
• Here every thing will be performed by sending as messages.
• Small and uniform language
  •     Syntax fits on one sheet of paper  
•  Large library of reusable classes Basic Data Structures, GUI classes, Database Access, Internet, Graphics
• Advanced development tools
  • Browsers, GUI Builders, Inspectors, Change Management Tools, Crash Recovery Tools, Project Management Tools
• Interactive virtual machine technology
  • Truly platform-independent
• Team Working Environment
  Releasing, versioning, deploying.

• We will see how a simple, uniform object model enables live, dynamic,interactive software development.

                                      You do not have to know everything!!! 

Try not to care — Beginning Smalltalk programmers often have trouble because they think they need to understand all the details of how a thing works before they can use it. This means it takes quite a while before they can master

One of the great leaps in OO is to be able to answer the question “How does this work?” with “I don’t care”.

• Here in virtual machine all the Objects exist in a persistent image [+ changes]
• It is an Incremental compilation
