I have an instance of a Class named P
const stringifyObject = require('stringify-object');
JSON.parse(stringifyObject(P));
Which returns the following error:
_readableState: {
^
SyntaxError: Unexpected token _ in JSON at position 3
at JSON.parse (<anonymous>)
Object to string : JSON.stringify
var a = {a:"2da",b:"xfgsfg"}
console.log(JSON.stringify(a))
String to Object: JSON.parse
var s = '{"a":"2da","b":"xfgsfg"}';
console.log(JSON.parse(s))
The NPM package stringify-object doesn't produce a JSON compliant string. You can use the built-in JSON.stringify to get a string, and JSON.parse to turn it back into an object.
const obj = {a: 1};
const str = JSON.stringify(obj); // '{"a":1}'
const deserialisedObj = JSON.parse(str); // {a: 1}
obj.a === deserialisedObj.a; // true
JSON.parse. It will throw an exception if you pass an invalid JSON string into it.
