While Microsoft focuses on an 3.1 incremental improvement for ECMAScript in IE 8, Brendan Eich (CTO of Mozilla and father of JavaScript) is developing the Tamarin ECMAScript engine from Flash (donated to open source by Adobe) for Microsoft's Internet Explorer, to ensure the world goes to the ECMA4 level with JavaScript 2.0 before 2009.Clever, commissioning the same ActiveState developer whom Microsoft did (for Perl and Python engines) to wire their JavaScript into IE. Only the code is not just Mozilla's; it was born of Adobe, owner of Photoshop and Flash, who has motive & means for its worldwide distribution.
Addendum: See the difference.
