[jQuery] Understanding JSON

[jQuery] Understanding JSON


I am trying to understand JSON, and could use a little help.
So, if I have something like:
{
"firstName": "John",
"lastName": "Smith",
"address": {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": 10021
},
"phoneNumbers": [
"212 555-1234",
"646 555-4567"
]
}
How would I use jQuery to write the values onto a page? And how do
you go the other way, taking values and serializing them into JSON to
be sent to the server?
Thanks!
