[Javascript] Memory Useage

[Tim Makins]

I have a requirement for quite a bit of data on a page, to be accessed from
Javascript. For instance, 6000 names, each with lat/lon coordinates,
accessed from a series of drop-downs. The easy way would be to store them in
an array, but I am a bit concerned that  viewer's computers might not be
able to cope. Am I right to think this, or is it not a problem ?
