Using json.stringify() alone good but it can’t save unsupported data ,
var keepacopy = json.stringify(arry);
this is an example above , it could keep a copy but some stuffs might not be supported, The solution is to use is
json.parse(json.stringift ()) ,
var keepacopy =
all thought it takes little time but it helps converted unsupported data into supported data .
json.parse takes a json string and change into a java script object.
