Am I right in thinking that Javascript applications are single
threaded? So I don't have to worry about adding something to a list
while at the same time processing the list? That is, if I get a cound
of the items and do a for loop on them, nothing can jump in
unexpectedly and add another item or remove one or something. (Perhaps
if I async something then that might cause issues, but I'm assuming
simple code.)

If it is possible, what is the "critical section" equivalent?

Matthew,

Yep, single-threaded, all the way.

If you are interested, it's possible to do multithreaded with EWB using Web Workers.  The way it works you do not have to worry about concurrency because there is no sharing of objects, just message passing.  

But unless you've gone to the trouble of including Web Workers, there is no worry about concurrency.
