Preface

In times gone by, JavaScript was used to provide minor enhancements to the Web in order to decorate pages with amusing effects or to validate user input. Slowly but surely, as browsers implemented faster JavaScript engines and new features and as developers and engineers came up with new techniques and ideas, JavaScript became near-ubiquitous in providing the functionality that end users have come to expect. With Ext JS, you have a toolset that allows you to build advanced JavaScript applications, but with great power comes great responsibility.

An application architect is the guiding hand of a project. They help to ensure that client expectations are met, timescales are achieved, and costs are contained. While juggling these requirements, the architect must provide the foundations for a technically successful project consisting of high quality, understandable code.

In Ext JS Application Development Blueprints, we'll go through the theory and practice of designing and building Ext JS applications. Over the next 11 chapters, you'll learn how Ext JS gives developers the key to a professionally designed software project and how to take this knowledge and use it in a range of real-world scenarios.
