    The basic rules from yslow/page speed (and when to break them)
    Tools for finding bottlenecks and slow javascript
    Common javascript performance patterns and how to fix them
    Architectural and design approaches to improve performance
    Considerations for Mobile performance
    Performance features in HTML5 and Rails 3

  • CoffeeScript: A New Brew

    by David L Kinney

    JavaScript is the assembly language of the web, and the first generation of higher-level languages built on top of that foundation has arrived. CoffeeScript is an exciting entry in this nascent field, embracing the best of JavaScript, extending it with collection operators, and wrapping it all in a more succinct, Ruby-ish grammar. CoffeeScript’s benefits have proven so compelling that it is supported in the core of Rails 3.1. We will introduce CoffeeScript’s core syntax – starting with a JavaScript function and tearing it apart until it’s an elegant few lines of CoffeeScript. Then we will cover CoffeeScript’s improvements for object-oriented programming, and finally review how CoffeeScript is used in a Rails 3.1 project.
