#import <CkoJsonObject.h>
#import <CkoJsonArray.h>

CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json Load: @"{ \"name\": \"John\", \"marbles\": 100 }"];

CkoJsonArray *jarr = [[CkoJsonArray alloc] init];
[jarr Load: @"[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Luther\"} ]"];

// Copy the contents of jar to a new array member named "stuff".
// Insert the array at the 2nd position
[json AddArrayCopyAt: [NSNumber numberWithInt: 1] name: @"stuff" jarr: jarr];

NSLog(@"%@",[json Emit]);
// Expected output is:  {"name":"John","stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Luther"}],"marbles":100}

// Note: The contents of the array were copied.
// If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
// For example:
[jarr AddIntAt: [NSNumber numberWithInt: -1] value: [NSNumber numberWithInt: 2020]];
NSLog(@"%@",[jarr Emit]);
// Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Luther"},2020]

NSLog(@"%@",[json Emit]);
// Remains unchanged: {"name":"John","stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Luther"}],"marbles":100}
