JSON is often pronounced as “JASON”. It stands for Javascript Object Notation and is a light weight way to describe hierarchical data. A lot of information on JSON can be found in the wikipedia and json.org. I often find the best way to learn is through examples. For the sake of simplicity, I will use one of the example found in wikipedia for explaination.
This is a typical JSON code returned from the server:
{
"firstName": "John",
"lastName": "Smith",
"address": {
"city": "New York, NY",
"zipCode": 10021,
"street": "21 2nd Street"
},
"phoneNumbers": [
"212 732-1234",
"646 123-4567"
]
}
