Jython is an implementation of the Python programming language written in 100% pure Java, so it runs under any compliant Java Virtual Machine. The secret to Jython's popularity lies in the combination of Java's librariesand tools with Python's rapid development capabilities. With Jython, you can write Python programs that integrate seamlessly with any Java code. And like Python, Jython can be used interactively, so you can get immediate results as you are programming.Jython Essentials provides a solid introduction to the Python language, offering a brief but thorough tour of the Python concepts you'll need to understand to use Jython effectively. The book makes frequent comparisonsbetween Python and Java, with special emphasis on the different object-oriented semantics of the two languages, so Java programmers can quickly get up to speed with Jython.Jython Essentials also covers the various ways in which Jython and Java can interact. For example, Jython code can create instances of pre-existing Java classes and call methods in those instances. You can write Jython classes that are direct subclasses of existing Java classesand use introspection to discern the capabilities of JavaBeans components. This book provides examples of using Jython with existing Java libraries, including the Swing GUI toolkit, the JDBC database API, the Servlet API, and various XML tools. And finally, the book shows howJython can be used as a scripting language within a Java program.With Jython Essentials, you have everything you need to start creating applications that mix the best of Python's interactivity and Java's robust libraries.

If you are designing websites and need an introduction to programming with the scripting language of the Web, Brilliant Javascript will show you how to use basic javascript programming to to improve the functionality and design of your webpages, validate forms, detect browsers, create cookies, and much more. Summary JavaScript is a critical component of nearly all web pages and web applications, and is the most popular scripting language on the internet, working in all major browsers, such as Internet Explorer, Mozilla, Firefox, Netscape, and Opera. It is a very powerful language but often overlooked as such. For years it has been used primarily for two things – validating form entries, and image rollovers. Yet there is much more under the hood. JavaScript is as powerful and comprehensive as any other development language. JavaScript gives HTML designers a programming tool- HTML authors are normally not programmers, but JavaScript is a scripting language with a very simple syntax! Almost anyone can put small "snippets" of code into their HTML pages. Brilliant JavaScript will take the reader through the necessary introductory material, and build on this to present practical applicable methods involving text, maths and numbers, and much more. Further tips will be presented in boxouts and text alerts . The book will follow a progression of knowled≥ however will be modular in approach. A reader can jump right to the task(s) they need to learn and use. The step by step approach will make it easy to follow how JavaScript is written and implemented – something that many developers struggle with when it comes to JavaScript’s cryptic syntax.

Despite using them every day, most software engineers know little about how programming languages are designed and implemented. For many, their only experience with that corner of computer science was a terrifying "compilers" class that they suffered through in undergrad and tried to blot from their memory as soon as they had scribbled their last NFA to DFA conversion on the final exam. That fearsome reputation belies a field that is rich with useful techniques and not so difficult as some of its practitioners might have you believe. A better understanding of how programming languages are built will make you a stronger software engineer and teach you concepts and data structures you'll use the rest of your coding days. You might even have fun. This book teaches you everything you need to know to implement a full-featured, efficient scripting language. You'll learn both high-level concepts around parsing and semantics and gritty details like bytecode representation and garbage collection. Your brain will light up with new ideas, and your hands will get dirty and calloused. Starting from main(), you will build a language that features rich syntax, dynamic typing, garbage collection, lexical scope, first-class functions, closures, classes, and inheritance. All packed into a few thousand lines of clean, fast code that you thoroughly understand because you wrote each one yourself.
