JavaScript uses a very rich JSON format, and if you want to store it locally, you can call Json.stringify () to convert it directly to a string. After reading it, call Json.parse () to convert the string to JSON format, as follows:1 var details = {Author: "Isaac", "description": "Fresheggs", "rating": 100};2 Storage.setitem ("Details", json.stringify (Details));3 details = Json.parse (Storage.getitem ("Details"));JSON objects are basically supported
