Scala runs on the Java platform (Java virtual machine) and is compatible with existing Java programs. [15] As Android applications are typically written in Java and translated from Java bytecode into Dalvik bytecode (which may be further translated to native machine code during installation) when packaged, Scala's Java compatibility makes it well-suited to Android development, the more so when ...
It aims to optimize developer productivity by using convention over configuration, hot code reloading and display of errors in the browser. [2] Support for the Scala programming language has been available since version 1.1 of the framework. [3] In version 2.0, the framework core was rewritten in Scala.
As Scala program code executes within the Java virtual machine (JVM), any existing Java library and web container can be used in running Lift applications. Lift web applications are thus packaged as WAR files and deployed on any servlet 2.4 engine (for example, Tomcat 5.5.xx, Jetty 6.0, etc.).
sbt is the de facto build tool in the Scala community, [6] used, for example, by the Scala 2 and Scala 3 compilers themselves, [7] [8] Play Framework, and Lichess, a popular chess server. The sbt project is "bootstrapped" — it uses sbt to build itself and considers dogfooding a positive feature.
Some of these languages are interpreted by a Java program, and some are compiled to Java bytecode and just-in-time (JIT) compiled during execution as regular Java programs to improve performance. The JVM was initially designed to support only the language Java. However, over time, ever more languages were adapted or designed to run on the Java ...
Akka is a source-available toolkit and runtime simplifying the construction of concurrent and distributed applications on the JVM.Akka supports multiple programming models for concurrency, but it emphasizes actor-based concurrency, with inspiration drawn from Erlang.
Unlike the stand-alone Hello World application for Java, there is no class declaration and nothing is declared to be static. When the program is stored in file HelloWorld.scala, t
Other functional programming languages that have seen use in industry include Scala, [120] F#, [18] [19] Wolfram Language, [7] Lisp, [121] Standard ML [122] [123] and Clojure. [124] Scala has been widely used in Data science, [125] while ClojureScript, [126] Elm [127] or PureScript [128] are some of the functional frontend programming languages ...
