@if (@_jscript_version == 10)
document.write("You are using IE10");
According to Wikipedia IE10 will use JScript 10.
JScript 10 seems to have a whole bunch of new proprietary extensions to EcmaScript 5.
Is the version of the EcmaScript engine (10) in IE10 related to JScript 10.0 ?
Does IE10 bring in a whole load of proprietary extensions like strict typing, etc?
