I was reading through Javascript overview on a webiste that stated following:
1) JavaScript can not be used for Networking applications because there is no such support available.
2) JavaScript doesn't have any multithreading or multiprocess capabilities.
My Questions:
1) Which kind of 'Networking Applications' are we talking about?
2) What is multithreading and multiprocessing capabilities author is talking about ?
Thanx.
Can you include a link to the article?
Also, #2 is no longer true as there are WebWorkers.
1) Which kind of 'Networking Applications' are we talking about?
Unlike JavaScript, server side code can do things like connect to a remote host over the network. Such as send an ICMP request, perform a DNS lookup, query a SQL server, etc.. This is a limitation of JavaScript.
@JorgeM: I got it . . . What about multithreading and multiprocessing ?
As mentioned above webworkers mitigates the single threaded nature of javascript.
Come to think of it, #1 should be able to be done through websockets, no (to a limited extent that is)?
Actually, all three points from that page are no longer valid.

Obviously there are still limitations as to what browser supports what, but this technically is possible today.
That was enlightening. helped a lot.
thanx guys .
