Earlier quoted context omitted.
What is the connection between browser fragmentation and coffescript syntax? Coffescript was born to have a lighter JavaScript-like syntax, not to remove browsers fragmentation.
the connection is between fragmentation and claim that ecmascript and js 1.8 were released and everything magically became great in december 2009 as was implied by the grandparent.
I implied nothing, I asked you a question. Might have been a bit open ended but you made a claim that did not reflect with my reality. So I did a reality check.
If there was a "magic" moment I will give chrome released late 2008 and firebug 1.4 released early 2009 the attribution for a turning point in webdev.
