A JSON object is a collection of zero or more key-value pairs called object members. The collection is wrapped in a pair of curly brackets. The key and value are separated by a single colon, while object members are separated with a comma character. The key is a string. The value can be any primitive or complex JSON data type. The structure of a JSON object is shown in the following figure:

The member name within a JSON object does not need to be unique. The following strings show a JSON text representing an object:

{ 
"Name":"Mila Radivojevic",  
"Age":12,  
"Instrument": "Flute" 
} 
{} 
{ 
"Song":"Echoes",  
"Group":"Pink Floyd",  
"Album":{ 
"Name":"Meddle",  
"Year":1971 
} 
} 
{ 
"Name":"Tom Waits", 
"Name":"Leonard Cohen" 
} 

Since the value can be any data type, including an object or an array, you can have many nested layers. This makes JSON a good choice for even complex data. Note that white spaces are allowed between the key and the value.
