This Week in JavaScript Performance

by | May 01, 2012

 This Week in JavaScript Performance summarizes recent web postings related to JavaScript performance. Watch for it on the Monitor.Us blog at the beginning of each week.

Cloud Computing – Questions & Answers

Author: Anil Radhakrishna.   Publisher: Anil Radhakrishna.This article is a point-form beginner’s guide to cloud computing, written in Q&A format. Not everything is as cut-and-dried as the article implies, but it is a good ramp-up for anyone who is just starting down the path of cloud computing and software as a service (SaaS).

Chrome – the Most Popular Browser?

Author: daleV.   Publisher: Geek Gumbo.As Chrome takes the lead away from Firefox, this article laments Chrome’s memory usage and its developer tools’ ease of use. Some performance specs are provided. Since DOM/CSS performance seems to be critical in many cases, I was surprised to see that both Chrome and Firefox were left in the dust in this category. Can you guess which browser beat them out? [P.S. – I love the image at the top!]

5 years later: print CSS still sucks

Author: Stoyan Stefanov.   Publisher: Stoyan Stefanov.This article revisits a 5-year-old tip that warned us that media=”print” blocks rendering even though the stylesheet to which it applies is not used until after the page is fully rendered. Stoyan finds that this is still a problem, proclaims Opera to be the “least bad”, and offers a workaround.

JavaScript in the Enterprise

Panelists: Douglas Crockford, Laurent Ribardière, Joe McCann, and Christoph Dorn.   Publisher: wakandasoft.This panel discussion asks and attempts to answer the question: Is JavaScript ready for enterprise environments (maybe it should ask whether enterprise environments are ready for JavaScript). It was recorded back in October, but it makes it into This Week in JavaScript Performance because Douglas Crockford posted a link to it a few days ago.

JSCheck at GitHub

Author: Douglas Crockford.   Publisher: Douglas Crockford.Douglas Crockford committed JSCheck, a public domain, specification-driven testing tool for JavaScript. JSC was inspired by QuickCheck, a testing tool for Haskell developed by Koen Claessen and John Hughes.

The performance of localStorage revisited

Author: Nicholas C. Zakas.   Publisher: Nicholas C. Zakas.This article continues the ongoing discussions about localStorage. It concludes that reads and writes are not significant performance issues, but that the initial data load may significantly delay time to interactivity. It points out that empirical measurements are necessary, but not yet available. [JavaScript’s single-threaded nature and its inability to set execution priorities are once again called on the carpet.]

Design Patterns in Javascript (JSJ 12)

Panelists: Addy Osmani, Jamison Dance, Joachim Larsen, and Charles Max Wood.   Publisher: JavaScript Jabber.This 48 minute podcast discusses design patterns in general and Addy’s free book in particular.

Performance aspects of Google’s HTML/CSS Style Guide

Author: Billy Hoffman?   Publisher: Zoompf.This article examines Google’s new HTML/CSS Style Guide from a performance standpoint.

5 Things They Told You Not to Use in JavaScript

Author: Thomas Fuchs.   Publisher: Mir.Aculo.us.This article takes exception to five JavaScript performance tips. I look forward to seeing test results (perhaps on jsperf.com) to prove or disprove some of these conclusions.

About Warren Gaebel

Warren wrote his first computer program in 1970 (yes, it was Fortran).  He earned his Bachelor of Arts degree from the University of Waterloo and his Bachelor of Computer Science degree at the University of Windsor.  After a few years at IBM, he worked on a Master of Mathematics (Computer Science) degree at the University of Waterloo.  He decided to stay home to take care of his newborn son rather than complete that degree.  That decision cost him his career, but he would gladly make the same decision again. Warren is now retired, but he finds it hard to do nothing, so he writes web performance articles for the Monitor.Us blog.  Life is good!
