BestTechVideos: Tag javascript Videos

Google Tech Talks
November, 14 2007

ABSTRACT

After eight years of work in the standards committee, JavaScript will soon get an update. We present the highlights and rationales of the proposed changes to JavaScript.

The fourth edition of the ECMAScript (JavaScript) language represents a significant evolution of the third edition language, which was standardized in 1999. ES4 is compatible with ES3 and adds important facilities for programming in the large (classes, interfaces, namespaces, packages, program units, optional type annotations, and optional static type checking and verification), evolutionary programming and scripting, data structure construction, control abstraction (proper tail calls, iterators, and generators), and introspection. Improved support for regular expressions and Unicode, richer libraries, and proper block scoping are also added.

ABSTRACT

Yahoo!'s Exceptional Performance Team has identified 14 best practices for making web pages faster. These best practices have proven to reduce response times of Yahoo! properties by 25-50%. They focus on the front-end, for example, why it's bad to use "@import" for including stylesheets and why ETags disable browser caching. In this talk I'll go in-depth on these best practices and the research behind them. I'll also demonstrate YSlow and do some live performance analysis of popular web sites.
