In general, unless your array is very large or you search it a lot, a
client-side loop is just so damn fast why bother playing games?

And if it IS very large or you search it a lot why not set up a hash table?
Then it's just "if ( myHash["Jane"] ) {};" Instant results with no fuss.

Just my opinion of course - which doesn't change the fact that McKirahan's
solution will, indeed, work just fine. ;^)
