Does javascript object allow for duplicate keys?

Does JavaScript object allow for duplicate keys, if not how would you add keys that have the same name but different values?

Thanks!

Sorry, misread your question.

No, JavaScript objects cannot have duplicate keys. The keys must all be unique. There is a good thread on Stack Overflow on this topic.

(It is titled with 'associative array', but it really is about a JS Object).

Thanks for the help! So if I use unique identifiers, what is the best syntax for that? pipeLength1: pipeLength2:

is their a better way than this?
