JavaFX interesting script features

Recently I have started to read about JavaFX. There are many various opinions about this technology... so I decided to take a look on some basics to get any opinion on my own. As a programmer I prefer some 'code-meat' in my IDE rather than playing with GUI, so "Learning the JavaFX Script Programming Language - Tutorial Overview" was my very first guest in browser ( http://download.oracle.com/javafx/1.3/tutorials/core/ ). Code examples are copied from this tutorial.

I just want to share with you with some basic techniques which made 'nice/strange' feeling in my mind ; ) I couldn't run JavaFX brush for SyntaxHighlighter plugin, so some colors dont fit well to code - sorry for that.

Tired of 'plusing' or appending strings? Join them using binding:

def thirdVar = "{one}{two}";

You can even use 'if' statements in line to build string:

var s = "The answer is {if (answer) "Yes" else "No"}";

Use dynamic types if you admire flexibility...

def numOne = 1.0; 
def numTwo = 1;   

...change it to static if you are big fan of clear-intention-code:

def numOne : Number = 1.0;
def numTwo : Integer = 1;

Somehow each introduction of new language contains some mind-twisters about collections/arrays. JavaFX is not an exception, but authors named this structure as 'sequence':

def nums = [1,2,3,4,5];
//sequence with numbers only greater than 2
def numsGreaterThanTwo = nums[n | n > 2];

...
//reverse values in sequence
var nums = [1..5];
nums = reverse nums; // returns [5, 4, 3, 2, 1]

Lets take sequence which contains strings. Do you want to insert new string in specific place? Not a big deal, really. Sql-developers would love that:

def weekDays = ["Mon","Tue","Wed","Thu","Fri"];
insert "Thu" before days[2];
...
delete "Sun" from days;

Nice feature is defining sequences with range syntax, but its not the end - you can easily set interval for this range:

var num = [0..5];
var nums = [1..10 step 2];
println(nums);//output: [ 1, 3, 5, 7, 9 ]

Coding in JavaFX seems easy to learn - its the most important when you need to kick start your project in new technology.

I have some GUI tutorials after me, but too less to consider JavaFX as concurent to any technology made for client-apps. Im going to look further into it, so stay tuned ;)
