We have been hearing about the "boost in JavaScript performance" news from various browser developers. Earlier, Mozilla was claiming an "up to 60% increase in JavaScript performance" in the new Firefox 4. Google says Chrome 10 was able to improve it by 12%, which is a comparable number as the Chrome JavaScript performance was already superior to other browsers.
What does this tell me? Two things: 1) JavaScript is holding strong as the main language in developing interactive user interfaces despite the existence of proprietary tools such as Adobe's Air and Microsoft's Silverlight. 2) A web browser is the platform of choice to host user interfaces, gradually replacing those of proprietary desktop software.
Will this run faster now?
