How do I know which version of Javascript I'm using?

Question

I\'m just reading this documentation about Javascript 1.2, but I\'m wondering which version of Javascript is being used in the most popular browsers.

Rather than finding which version you are using you can rephrase your question to "which version of ECMA script does my browser's JavaScript/JSscript engine conform to".

For IE :

alert(@_jscript_version);      //IE

Refer Squeegy's answer for non-IE versions :)
