Sometimes, you need to convert a JavaScript object to a plain string that is useful for storing object data in a database. In this tutorial, we will suggest two methods for converting an object to a string.
The JSON.stringify() method is used to convert object to string which is needed to send data over the web server. It converts the set of variables in the object to a JSON string:
Output:
{"siteName":"W3Docs", "bookName":"Javascript", "booksCount": 5}
The toString() method is also called when you need to convert the object into a string:
The JSON.stringify() method converts an object or value to a JSON string. JSON.stringify skips some JavaScript-specific objects, such as properties storing undefined, symbolic properties, and function properties.
The toString( ) method is called without arguments and should return a string. The string you return should be based on the value of the object for which the method was called so as to be useful.
