134 Part I: Core Ideas

Legal JSON number values have quite a range of forms, just as they do in JavaScript:

3

-1968

200001

• 0.9
  3333.409
  3e+1
  4E-2
  -0.45E+10

Arrays are just as they would be in JavaScript when containing only literals, a list of

values separated by commas:

array

[]value

,

An example of arrays in JSON follows:

["Larry", "Curly", "Moe", 3, false]

JSON objects are similar to the object literal format found in JavaScript except that the

properties will always be strings rather than identifiers:

object

{}string value

,

:

For example:

{"firstname": "Thomas", "lastname" : "Powell" , "author" : true,

"favoriteNumber" : 3 , "freeTime" : null}

JSON values can nest, thus the following more complex examples are legal JSON structures:

[ {"name" : "Larry" , "hair" : true },

{"name" : "Curly" , "hair" : false },

{"name" : "Moe" , "hair" : true }

]

{ "primaryStoogeNames" : ["Larry", "Curly", "Moe"],

"numberofStooges" : 3,

"alternateStooges" : [ {"name" : "Shemp", "original" : true } ,

{"name" : "Joe", "original" : false } ,

{"name" : "Curly Joe", "original" : false }

]

}
