Editing Java virtual machine (section)

===Transpilation to JavaScript===
With the continuing improvements in JavaScript execution speed, combined with the increased use of mobile devices whose web browsers do not implement support for plugins, there are efforts to target those users through [[Transpile|transpilation]] to JavaScript. It is possible to either transpile the source code or JVM bytecode to JavaScript.

Compiling the JVM bytecode, which is universal across JVM languages, allows building upon the language's existing compiler to bytecode. The main JVM bytecode to JavaScript transpilers are TeaVM,<ref>{{cite web |url = http://teavm.org/ |title = TeaVM project home page |publisher = Teavm.org |access-date = 2015-06-26 |archive-date = 2015-06-27 |archive-url = https://web.archive.org/web/20150627045343/http://teavm.org/ |url-status = live }}</ref> the compiler contained in Dragome Web SDK,<ref>{{cite web |url = http://www.dragome.com/ |title = Dragome Web SDK |publisher = Dragome.com |access-date = 2015-06-26 |archive-date = 2015-08-01 |archive-url = https://web.archive.org/web/20150801074231/http://dragome.com/ |url-status = live }}</ref> Bck2Brwsr,<ref>{{cite web |url = http://wiki.apidesign.org/wiki/Bck2Brwsr |title = Bck2Brwsr - APIDesign |publisher = Wiki.apidesign.org |access-date = 2015-06-26 |archive-date = 2015-06-27 |archive-url = https://web.archive.org/web/20150627062724/http://wiki.apidesign.org/wiki/Bck2Brwsr |url-status = live }}</ref> and j2js-compiler.<ref>Wolfgang Kuehn (decatur).

Leading transpilers from JVM languages to JavaScript include the Java-to-JavaScript transpiler contained in [[Google Web Toolkit]], Clojurescript (Clojure), GrooScript (Apache Groovy), Scala.js (Scala) and others.<ref>{{cite web |url = https://github.com/jashkenas/coffeescript/wiki/list-of-languages-that-compile-to-js |title = List of languages that compile to JS · jashkenas/coffeescript Wiki · GitHub |publisher = Github.com |date = 2015-06-19 |access-date = 2015-06-26 |archive-date = 2020-01-31 |archive-url = https://web.archive.org/web/20200131233044/https://github.com/jashkenas/coffeescript/wiki/List-of-languages-that-compile-to-JS |url-status = live }}</ref>
