Its very simple and easy way to create JSON String value and share. The second argument is a really helpful way of either modifying or specifying only the properties that we want to store, save or send to a server. JSON Stringify Online helps convert string value to JSON String using JSON.Stringify(). That's because there is no intended modification or filtering of the object. Now you understand why null is usually passed as the second argument. Using an array replacer won't do anything. if you return null, the output will be null.if you return undefined or a function, the output will be undefined.if you attempt to do any filtering, it won't work.if you attempt to do any modification, it won't work.When you use the function replace on an array, a few things happen: It provides a format for storing and transporting data. The replacer method doesn't work as you would expect on array values. The JavaScript JSON is an acronym of JavaScript Object Notation. Using our replacer, we don't expect to see the profession key because it doesn't exist in the object.įrom the result above, we can see how the object has been filtered. The object has five keys: name, id, age, type and obj.
