Why reinvent the wheel every time you run into a problem with JavaScript? This cookbook is chock-full of code recipes for common programming tasks, along with techniques for building apps that work in any browser. You'll get adaptable code samples that you can add to almost any project--and you'll learn more about JavaScript in the process. The recipes in this book take advantage of the latest features in ECMAScript 2020 and beyond and use modern JavaScript coding standards. You'll learn how to: Set up a productive development environment with a code editor, linter, and test server Work with JavaScript data types, such as strings, arrays, and BigInts Improve your understanding of JavaScript functions, including arrow functions, closures, and generators Apply object-oriented programming concepts like classes and inheritance Work with rich media in JavaScript, including audio, video, and SVGs Manipulate HTML markup and CSS styles Use JavaScript anywhere with Node.js Access and manipulate remote data with REST, GraphQL, and Fetch Get started with the popular Express application-building framework Perform asynchronous operations with Promises, async/await, and web workers

Problem solving with JavaScript is a lot trickier now that its use has expanded considerably in size, scope, and complexity. This cookbook has your back, with recipes for common tasks across the JavaScript world, whether you're working in the browser, the server, or a mobile environment. Each recipe includes reusable code and practical advice for tackling JavaScript objects, Node, Ajax, JSON, data persistence, graphical and media applications, complex frameworks, modular JavaScript, APIs, and many related technologies. Aimed at people who have some experience with JavaScript, the first part covers traditional uses of JavaScript, along with new ideas and improved functionality. The second part dives into the server, mobile development, and a plethora of leading-edge tools. You'll save time - and learn more about JavaScript in the process.Topics include: Classic JavaScript: Arrays, functions, and the JavaScript Object Accessing the user interface Testing and accessibility Creating and using JavaScript libraries Client-server communication with Ajax Rich, interactive web effects JavaScript, All Blown Up: New ECMAScript standard objects Using Node on the server Modularizing and managing JavaScript Complex JavaScript frameworks Advanced client-server communications Visualizations and client-server graphics Mobile application development

The Resource Description Framework (RDF) is a structure for describing and interchanging metadata on the Web. Practical RDF explains RDF from the ground up, providing real-world examples and descriptions of how the technology is being used in applications like Mozilla, FOAF, and Chandler, as well as infrastructure you can use to build your own applications. This book cuts to the heart of the W3C's often obscure specifications, giving you tools to apply RDF successfully in your own projects.

"Gain "braids together two stories on very different scales. In one, Laura Body, divorced mother of two and a real-estate agent in the small town of Lacewood, Illinois, plunges into a new existence when she learns that she has ovarian cancer. In the other, Clare & Company, a soap manufacturer begun by three brothers in nineteenth-century Boston, grows over the course of a century and a half into an international consumer products conglomerate based in Laura's hometown. Clare's stunning growth reflects the kaleidoscopic history of America; Laura Body's life is changed forever by Clare. The novel's stunning conclusion reveals the countless invisible connections between the largest enterprises and the smallest lives.

"Adding Ajax" is ideal for intermediate to advanced web developers who are worried and confused about Ajax, thinking that it will force them to start over with their craft. This refreshing guide will calm those fears by offering an entirely new approach to the topic. Rather than introduce Ajax as a completely new way of doing things, this book shows you how to integrate Ajax with existing sites, and does so by building to Ajax rather than building from an Ajax foundation. By reading this book, you will learn how Ajax allows you to create "rich" web applications, but more importantly, you'll see how the practices you already follow feed right into Ajax - and that, in most cases, you already work with the technologies involved. Adding bits and pieces often makes much more sense than tearing down and rebuilding, and you'll learn to integrate Ajax with your usual process. This book: provides an overview of the Ajax technologies, and the importance of developing a strategy for change to your site before sitting down to code; offers nuts and bolts coverage of the heart and soul of Ajax: how to work with the XMLHttpRequest object; introduces and demonstrates several of the more important Ajax libraries, including Prototype, script.aculo.us, rico, Mochikit, and so on; and gets into the interactive element that is Ajax, including how to work with events and event handlers that work across browsers. It also explores the concept of web page as space, and covers three popular approaches to managing web space; explains how to make data updates, including adding new data, deleting, and making updates, all from within a single page; explore the effects Ajax has on the Web -- breaking the back button, losing browser history, dynamic effects that disappear when the page is refreshed, and more; covers advanced CSS effects, including drag and drop 'scroll bars', pagination, and the use of SVG and the Canvas object; and explores mashups - Ajax's ability to bring in different web services, and combine the data in any number of ways, directly in our web pages. At the end of "Adding Ajax", there's reflection on whether starting over might be a fun idea, but by then you should be much more comfortable with it.
