In JavaFX script any sequence of characters enclosed in “french quotes” is treated as a lexical identifier, and thus may be used as a valid name of a variable, function, or class. var <<this is a variable>> = "Hello World"; <<this is a variable>>.toUpperCase(); This mechanism may be used to access Java methods which conflict with JavaFX keywords, for example: var textField = new javax.swing.JTextField(); textField.<<insert>>("Hello World"); This mechanism is also useful for code generators in translating symbols from other languages having incompatible lexical rules to JavaFX script.
