Scala Chinese Manual Scala Getting Started and Advanced

Scala is also a functional language, and its functions can also be used as values. Scala provides a lightweight syntax for defining anonymous functions, supports higher-order functions, allows nesting of multi-level functions, and supports currying. Scala's Case Class and its built-in pattern matching are equivalent to the Algebraic Type commonly used in functional programming languages.

Scala Class is a series of lectures launched by Twitter to help experienced engineers become effective Scala programmers. Scala is a relatively new language but borrows many familiar concepts. Therefore, the lectures in the course assume that the audience knows these concepts and show how to use them in Scala. We've found this to be an effective way to get new engineers up to speed quickly. The website contains written materials that accompany these lectures and are also useful in their own right.

Method

We believe that the most meaningful way to teach is not to think of Scala as an improved Java, but as a new language. So here we will not introduce the experience of using Java, but will focus on the interpreter and the "object-functional" style, as well as our programming style. Special emphasis is placed on maintainability, clear expression, and taking advantage of the type system.

Most courses require no additional software beyond Scala's interactive command line. Readers are encouraged to study sequentially and not only. Let these courses be your starting point for exploring Scala!
