Somewhere in a
prototype extension library, I noticed a shorthand (can't find it now) for
testing whether an parameter is in a set of values.
The set was in an
object or an array (don't remember) and resulted in an easy
shorthand.
Maybe something
like:
function myFunc
(parm1) {
if( {2:2,
5:5, 9:9, 17:17}[parm1] ) { // Is parm1 equal to 2, 5, 9 or
17?
This seems more
verbose that what I recall.
What's a
good shorthand technique for testing whether a value is in a
set?
