replaceDuplicateKey:false is not working

A possible workaround can be -
                    if (properties.replaceDuplicateKey) {
                        bucketEntry[0] = key;
                        oldValue = bucketEntry[1];
                        bucketEntry[1] = value+", "+oldValue;
                    }
                    else{
                        bucketEntry[1] = value;
                    }

But this is not a good way to do so. I think  if there exist duplicate values 
then it will return an array other than the plain object.

This is the expected behaviour. If you put a new value for an existing key, the 
value should always be replaced, which is how all hash table implementations 
that I've used work. The replaceDuplicateKey determines what happens to the key 
that is stored in that situation. The following example illustrates this:

var key1 = { foo: 1, name: "key1" }, key2 = { foo: 1, name: "key2" };

function keysEquals(k1, k2) {
    return k1.foo == k2.foo;
}

var hash1 = new Hashtable( { equals: keysEquals, replaceDuplicateKey: true } );
hash1.put(key1, 1);
hash1.put(key2, 2);
console.log(hash1.keys()[0].name); // key2

var hash2 = new Hashtable( { equals: keysEquals, replaceDuplicateKey: false } );
hash2.put(key1, 1);
hash2.put(key2, 2);
console.log(hash2.keys()[0].name); // key1
