If you're a web developer with previous JavaScript and DOM scripting experience, Accelerated DOM Scripting with Ajax, APIs, and Libraries is perfect for you to take your knowledge to the next level.This book is about JavaScript and using the document object model—the conduit to the HTML document. This book is not about learning how to program JavaScript from scratch. It starts with the assumption that you have done some JavaScript development before and understand the JavaScript syntax. This book builds on that knowledge to give you a deeper understanding of DOM scripting and how to apply that to your projects. It uses this new understanding to describe what JavaScript libraries are and show you how they can be applied to your project. The book will also explain Ajax and how best to plan and apply it to your projects. It explains how to build simple animation objects for adding movement to elements on the page. There are straightforward examples that demonstrate the techniques used throughout the book.JavaScript has seen a resurgence in popularity over the past few years, and with it has come an exploration of the power of the language as well as what it can do within the browser. This book will explain techniques new and old—such as closures, encapsulation, and inheritance—that many are using and how you can best apply them to your own projects.By reading this book, you should have a greater understanding of how JavaScript works and be able to use advanced concepts such as closures and event delegation to build more flexible applications for the Web. You'll walk away with a greater appreciation for JavaScript libraries and how they can simplify and speed up your development. You'll also be able to implement Ajax effectively into your site, create special effects, use JavaScript libraries, and know how best to apply these libraries to your projects.

Python is a versatile and powerful language that can be used for a wide variety of tasks. In this book, we''ll look at how Python can be used for various tasks that will make your life easier:
Python as a “glue” language: it helps us combine skills and programs we already know how to use by allowing us to easily convert data from one format to another. This means that we can take data in one format that we don’t have tools to manipulate and change it into data for tools that we’re comfortable with. Whether we need to process a CSV, web page, or JSON file, Python can help us get the data into a format we can use.Python for stitching together other things. Sometimes we need to do more than process the data in an Excel file we’ve been sent. For example, we may want to fetch some pages from the Web, or work with an online API, or control our computer itself (such as renaming a batch of files, or changing how our operating system works). Python is great at these tasks.Words and numbers. Python is a powerful tool that can be used to solve a wide variety of problems, both big and small. In this tutorial, we’ll explore how to use Python to answer questions, solve puzzles, and simulate various scenarios.Running someone else’s Python code. Unlike many other languages, Python actually comes with modules for all sorts of useful functions. But for the times when we want to do things not covered by the standard library, we can use PyPI, a vast collection of open-source software libraries, frameworks and applications that can be easily installed and used in Python projects. We''ll look at some examples.We’re also going to assume a little knowledge of Python and programming already—such as what a variable is, what a dictionary is, and how to import a module.
