[tw5] Re: Interesting test for unique string processing
Hi Arlen,
It would be interesting, what you try to prove here?
Accessing big arrays with a loop is probably always slower than accessing
an object element by name. The biggest difference probably is memory
consumption.

Hi,
If you are proposing this be used in the core or such perhaps it would be
better to raise this in the developer discussion's. Since as a rule
Javascript is not native in User interface but provides modules and plugins.
