If I had an array as such:
var myarray = []; myarray.push({ \"Name\": \'Adam\', \"Age\": 33 }); myarray.push({ \"Name\": \'Emily\', \"Age\": 32
Along with a single value like
myarray[0].address = "your address";
You could even add a nested property on the fly as below:
myarray[0].address = { presentAddress: "my present address..." };
and get the value as myarray[0].address.presentAddress;.
myarray[0].address.presentAddress;
