Java™ developers have historically perceived JavaScript as a toy
language, both too lightweight for real programming and too clunky to be of use as a
scripting alternative. And yet JavaScript is still around, and it's the basis of
exciting web technologies like GWT and Node.js. In this installment of Java
development 2.0, Andrew Glover explains why JavaScript is
an important tool for the modern Java developer. He then gets you
started with the syntax you need to build first-class applications for
today's web, including JavaScript variables, types, functions, and
classes.
Back in the early days of the Java platform, it wasn't unusual for journalists, and even occasionally newbie programmers, to confuse JavaScript and the Java language. Both languages were popularized due to their applicability to web programming, after all, and for a few years they ran neck-and-neck in the popular imagination. Most people today differentiate the two languages, but it's still common for Java developers to deride JavaScript as a toy language, not even fit for scripting. The thing is, JavaScript (much like the Java language) has lived on, and even evolved. It's the basis of client-side programming techniques like Ajax and server-side efforts like Node.js, and its importance for mobile application development is beginning to emerge. It's also the language that Java code compiles to in the very popular Google Web Toolkit, or GWT. more...
