JSON means JavaScript object Notation, which is a common format for data representation in JavaScript, and the JSON data format is much like the object in javascript:{"Name": "Value", "some": [1, 2, 3]}The difference is that, relative to the property name in the object, the key name in the JSON must be wrapped in quotation marks. This is only required in special attribute names when the object is famous:{"First name": "Dave"}.To parse a JSON data into a JavaScript object, it is best to use Json.

Try Redis: getting started with RedisOpening Redis is a NoSQL database that stores data using key-value pairs. Key-value pairs store data based on a key. Then you can use this key to retrieve the stored value. AvailableSETThe command uses the key 'servername' to store the value 'fid ': SET servername 'fido' In this way, the data is stored and can be used later.GETRetrieve the stored data: GET servername // return "
