The JavaFX Script programming language (hereinafter referred to as JavaFX) is a declarative, statically typed scripting language from Sun Microsystems, Inc. As mentioned on the Open JavaFX (OpenJFX) web site, JavaFX technology has a wealth of features, including the ability to make direct calls to Java technology APIs. Because JavaFX Script is statically typed, it also has the same code structuring, reuse, and encapsulation features -- such as packages, classes, inheritance, and separate compilation and deployment units -- that make it possible for your to create and maintain very large programs using Java technology.

More from experts:
JavaFX Script, is an open-source scripting language designed to facilitate rapid content authoring. JavaFX Script provides a highly-expressive syntax for declarative construction of 2D graphics and dynamic user interfaces. Although JavaFX Script is statically typed, the language is heavily inspired by popular dynamic programming languages like Python and incorporates compelling syntactic features like support for list comprehensions and first-class functions.
JavaFX isn't a completely independent runtime; it is essentially designed as a layer that sits on top of Java in order to make Java better-suited for rich application development. There are advantages and disadvantages to this approach. Sun clearly went to great lengths to make sure that JavaFX uses as much existing Java infrastructure as possible in order to simplify the process of integration. As a result, JavaFX feels like a very natural extension of the Java ecosystem. Developers can use Java libraries directly in JavaFX Script, and the language's declarative syntax for interface development is tightly bound to Swing and Java2D. The downside is that JavaFX Script doesn't really give developers the ability to do much they couldn't do already, its function is primarily to make existing Java technologies easier to use together.
As a result of JavaFX's dependence on existing Java technologies, developers with Java expertise will find that their existing skills easily translate over to JavaFX development. The broad availability of existing libraries for Java also ensures that a lot of useful functionality is available in JavaFX right out of the box. Additionally, since JavaFX runs on top of the JRE, it is highly portable and can target a wide variety of platforms.
Although JavaFX has a lot of potential, the technology also has a lot of weaknesses. JavaFX Script fixes many of Java's most frustrating syntactic deficiencies, but at the present time, very few convenience mechanisms are provided to support the kind of functionality currently required by modern interactive web applications. In particular, I think that JavaFX Script really needs some heavy syntactic sugar for consuming and manipulating remote XML and JSON content. One thing it does seem to handle relatively well, however, is integration of embedded HTML for application styling and content.
Wait and see how it progresses.......................
