On, Odersky and collaborators launched Typesafe Inc. On 17 January 2011, the Scala team won a five-year research grant of over €2.3 million from the European Research Council. Īfter an internal release in late 2003, Scala was released publicly in early 2004 on the Java platform, A second version (v2.0) followed in March 2006. Odersky formerly worked on Generic Java, and javac, Sun's Java compiler. It followed on from work on Funnel, a programming language combining ideas from functional programming and Petri nets. The design of Scala started in 2001 at the École Polytechnique Fédérale de Lausanne (EPFL) (in Lausanne, Switzerland) by Martin Odersky. The name Scala is a portmanteau of scalable and language, signifying that it is designed to grow with the demands of its users. It also has an advanced type system supporting algebraic data types, covariance and contravariance, higher-order types (but not higher-rank types), anonymous types, operator overloading, optional parameters, named parameters, raw strings, and an experimental exception-only version of algebraic effects that can be seen as a more powerful version of Java's checked exceptions. Unlike Java, Scala has many features of functional programming languages (like Scheme, Standard ML, and Haskell), including currying, immutability, lazy evaluation, and pattern matching. Martin Odersky has said that this turned out to be the most productive change introduced in Scala 3. Since Scala 3, there is also an option to use the off-side rule (indenting) to structure blocks, and its use is advised. Like Java, Scala is object-oriented, and uses a syntax termed curly-brace which is similar to the language C. On the JVM Scala provides language interoperability with Java so that libraries written in either language may be referenced directly in Scala or Java code. Scala can also be compiled to JavaScript to run in a browser, or directly to a native executable. Scala source code can be compiled to Java bytecode and run on a Java virtual machine (JVM).
Designed to be concise, many of Scala's design decisions are aimed to address criticisms of Java.
