Data Types
JSON data types are: null, Booleans, Strings, Numbers, Objects (which can be thought of as Maps) and Arrays.
null
Booleans
Booleans are represented as
true false
and they are not quoted.
Strings
Strings are represented as:
"this is a string"
and they are quoted. Always use double quotes ("), never use single quotes (').
Numbers
Numbers are represented as:
10
and they are not quoted.
Objects
Objects are enclosed in curly brackets "{}" and contain key/value pairs. The key and the value are separated by colon (":"). The pairs are delimited by commas (","):
{
"id" : 42,
"name" : "John Doe",
"married" : true
"kids" : [ "Alice", "Bob" ]
}
Arrays
Array elements are enclosed in brackets "[", and they are separated by commas:
[ "one element", "another element" ]
