In order to run the examples in this book, you will need to have a web server installed on your system to serve the code files. For example, you can use Apache or IIS or NGINX. In order to make the installation process of Apache easier, you can use more complete development environment solutions, such as XAMPP or WAMP Server.
In terms of technical proficiency, this book assumes that you already have some experience of working with jQuery, HTML, CSS, and JSON. All the code samples in the book use jQuery v2.2.0 and some of the chapters also discuss the respective implementation in jQuery v1.12.0, which can be used in case support for older browsers is needed.
