Learn about the most important concepts surrounding web development and demystify jQuery. This book gives you the confidence to abandon your jQuery crutches and walk freely with the power of the web API and JavaScript. Beyond jQuery doesn't just throw code at you - everything is explained in detail from the perspective of a jQuery developer. jQuery is often injected into web applications and libraries with no logical reason for pulling it in as a dependency. Many web developers don't really know when they need to use jQuery, and when they don't - it's just a standard step when setting up a new library or web application. But relying solely on jQuery as your window to the web leaves large gaps in your knowledge. This in turn results in frustration when the abstraction that jQuery provides "leaks" and exposes you to the native aspects of the browser. This book educates developers, reveals the magic behind jQuery, helps you solve common problems without it, and gives you more confidence to embrace the power of the web API and standardized JavaScript. What You'll Learn Use the web API and standardized JavaScript Determine when you need jQuery and when you don't Review common JavaScript utility functions Work with HTML elements Who This Book Is For Any web developer who is interested in learning how to live without jQuery, and deepening their understanding of web development.

You'll see how to create a set of reusable tools that unify and ease the scalar types of PHP. PHP has a rich history and a dominant place on the web.

We're all for getting stuff done, and to that end, the author has used Plain Ol' PHP for many years. It's always bugged him how procedural PHP is, in an ecosystem of OOP libraries and frameworks. So he decided to take a deeper look at building a stronger type system on top of PHP. That's the goal of this book.
