Are you like most developers, relying heavily on JavaScript to create interactive and responsive web applications? The problem is that all those lines of JavaScript code can slow down our applications. This book shows techniques and strategies for eliminating bottlenecks right from the programming stage. You will learn how to improve execution time, code loading, interaction with the DOM model, page lifecycle and much more!

• Improving execution time of JavaScript scripts
• Optimizing loading code on the page
