Scala source code can be compiled to [[Java bytecode]] and run on a [[Java virtual machine]] (JVM). Scala can also be compiled to [[JavaScript]] to run in a browser, or directly to a native executable. On the Italic text JVM Scala provides [[language interoperability]] with [[Java (programming language)|Java]] so that libraries written in either language may be referenced directly in Scala or Java code.<ref>{{cite web |url=https://www.scala-lang.org/old/faq/4 |title=Frequently Asked Questions: Java Interoperability |author=<!--Staff writer(s); no by-line.--> |website=Scala-lang.org |access-date=2015-02-06}}</ref> Like Java, Scala is [[Object-oriented programming|object-oriented]], and uses a [[Syntax (programming languages)|syntax]] termed ''[[List of programming languages by type#Curly-bracket languages|curly-brace]]'' which is similar to the language [[C (programming language)|C]]. Since Scala 3, there is also an option to use the [[off-side rule]] (indenting) to structure [[Block (programming)|blocks]], and its use is advised. [[Martin Odersky]] has said that this turned out to be the most productive change introduced in Scala 3.<ref>{{Cite AV media |people=Martin Odersky |date=17 June 2020 |title=Martin Odersky: A Scala 3 Update |medium=video |language=en |url=https://www.youtube.com/watch?v=Z0w_pITUTyU |archive-url=https://ghostarchive.org/varchive/youtube/20211221/Z0w_pITUTyU |archive-date=2021-12-21 |url-status=live|time=36:35–45:08 |publisher=YouTube |access-date=2021-04-24}}{{cbignore}}</ref>
Unlike Java, Scala has many features of [[functional programming]] languages (like [[Scheme (programming language)|Scheme]], [[Standard ML]], and [[Haskell (programming language)|Haskell]]), including [[currying]], [[immutability]], [[lazy evaluation]], and [[pattern matching]]. It also has an advanced type system supporting [[algebraic data type]]s, [[covariance and contravariance (computer science)|covariance and contravariance]], [[higher-order type operator|higher-order types]] (but not [[Parametric polymorphism|higher-rank types]]), [[anonymous type]]s, [[operator overloading]], [[Option type|optional parameters]], [[named parameter]]s, [[raw string]]s, and an experimental exception-only version of algebraic effects that can be seen as a more powerful version of Java's [[checked exception]]s.<ref>{{Cite web|title=Effect expt|url=https://docs.scala-lang.org/scala3/reference/experimental/canthrow.html|access-date=2022-07-31|website=scala}}</ref>
