JSON: Nested Array

See more JSON Examples

Here we have a JSON object that contains nested arrays. This example demonstrates how to access the contents of the nested arrays.

{
 "numbers" : [ 
    ["even", 2, 4, 6, 8], 
    ["prime", 2, 3, 5, 7, 11, 13] 
  ] }

; This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars).
; The presence of whitespace chars for pretty-printing makes no difference to the Load
; method.
