Older Documentation

The documentation below may be a bit outdated, but provides insights into the (historical) design principles of the language :

  • Brief Scala Tutorial: a 20 page introduction to scala and some of the basic concepts and a good place to start. You will find more code examples here.
  • Scala By Example: takes you through the Scala features with many examples. It does assume that you are already familiar with the basic Scala syntax and a basic understanding of functional programming. It is an excellent way to expand your knowledge and skill.
  • Scala Overview: this is a paper summarizing the features of the Scala Language in a formal and concise way. An excellent reference for language researchers or advanced programmers.
  • Java to Scala with the Help of Experts: a collection of some of the almost endless supply of tips available for Java programmers new to Scala. There are also mini-blog series designed to take you through many of the important features of the Scala language in a friendly way.
