When localizing JavaScript files in the application, you will need to create new JavaScript property files for each locale. The files for the default locale are named simply as *.js.properties. The files for other locales are identified by appending the locale identifier - after a separating "_" (underscore) character - between the .js extension and the .properties extension. For example, SomeJSFile.js_es.properties would be the name of the Spanish language version of SomeJSFile.js.properties file. This file will be automatically processed by a client build. Similar to the non JavaScript property files, if a particular property is not found by the application in SomeJSFile.js_es.properties file, then the property from the default properties file (SomeJSFile.js.properties) will be used.
