I'm sorry, but I don't understand your questions.
Maybe I can explain what these lines say:
1- this is a loop, like : "Take every pair of the Hash referenced as
HashtoBeTested"
Remember that a Hash is a collection of pairs. Each pair is composed of a key
and a value
2- for every pair, c
Hi Christophe
Thanks, but is there anything more to the syntax. Also how do you use that
optional context parameter with this within the loop and for what enhanced
value/processing does it give you?

If I understand well, what you're asking for is pretty close to what you
suggested in your original post:
hashToBeTested.each(function(pair){
if(valueToTest==pair.value){
hashToBeTested.unset(pair.key);
}
}

Hi, again
Sorry for being obtuse. But can someone help me and even understand how to
write a function and call it on a hash that will take a value, compare it
against each of the keys in the hash, on match delete the key/value, and
return the hash. tia.

Hi Alex
Thanks, but a newbie here so that was "drinking at a firehose". Let me
parse it to better understand.
First can you really invoke on two separate enumerable objects with that
[n,n1,n2] syntax? That is tremendous.
My problem is I need to first check the presence of a key before I unset it
Ah, I see. You can handle this using Enumerable's invoke. This code should
make it clear:
a = new Hash({ x : "foo", y : "bar" });
b = new Hash({ x : "zam", y : "moof" });
a.get("x");
"foo"
b.get("x");
"zam"
[a,b].invoke("get","x");
["foo", "zam"]
[a,b].invoke("unset","x")
["foo", "zam"]
a.
Sorry sudden send resume in this reply
Hello
I am having a difficult time trying to enumerate a hash to determine if a
give key is in the hash and if so delete it and its value.
If I could approach it index it would be
function remove(valueToTest, hashToBeTested){
