function chilkatExample() {

    var json = new chilkat.JsonObject();
    json.Load("{ \"name\": \"John\", \"marbles\": 100 }");

    var jarr = new chilkat.JsonArray();
    jarr.Load("[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]");

    // Copy the contents of jar to a new array member named "stuff".
    json.AppendArrayCopy("stuff",jarr);

    console.log(json.Emit());
    // Expected output is:  {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

    // 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(-1,2020);
    console.log(jarr.Emit());
    // Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

    console.log(json.Emit());
    // Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}
