JavaFX Script Keywords and Java Interoperability

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 textArea = new javax.swing.JTextArea();
  textArea.<<insert>>("Hello World", 0);

This mechanism is also useful for code generators in translating symbols from other languages having incompatible lexical rules to JavaFX script.

Ah, interesting! I've seen those in various examples before, but didn't know what they were. Thanks for the explanation!

insert(..) for JTextField???
It's interesting to see that creator of JavaFX doesn't know Java :-)

I've corrected the example. Thanks for pointing it out.

I know I'm little boring and you have more important and interesting things to do, but .. it's still incorrect.
There is no method insert(String) for JTextArea.
BTW I feel you really don't like Swing. Is it a main reason we have now so fascinating and so Swing-alien JavaFX?
