strict equality not just compares the value but the type also. I guess this
is more important when you rely on untyped variables, object.toString and
object.valueOf, as we did in AS1 and AS2. One situation, where strict
equality is used implicitely, is switch. At least this was the case in AS2.
It took people by surprise more than once, because normally AS2 converted
strings to numbers and vice versa when it made sense.
var value = "3";
switch( value )
{
case 3 : trace("we dont go here"); break;
default: trace("but here"); break;
}
if( value == 3 ) trace("this works in as2 at least because value is
converted to number.")
Cheers,
Ralf.

heading for "Language Elements" one of which is "Operators" The link above
