Check For Condition Matched Against A Set

Free Resource
Code by Laurens van der Oever -- http://laurens.vd.oever.nl/weblog/items2005/setsinjavascript/

function set () {
    var result = {};

    for (var i = 0; i < arguments.length; i++)
      result[arguments[i]] = true;

    return result;

Check something like so:

var typeInSet = nodeType in set(2, 3, 4, 7, 8);
