Encountering an Uncaught TypeError while attempting to parse JSON using JavaScript

Recently, I've been working on parsing JSON in JavaScript

{"success":{"id_user":"1",
"username":"nasir",
"password":"f30aa7a662c728b7407c54ae6bfd27d1"}}

I successfully parsed the JSON using the following code snippet

var obj = JSON.parse(result);  // result contains the JSON mentioned above
console.log(obj.success);      // to display the JSON in the console

However, I encountered an issue when trying to retrieve the value of the username element using the following code snippet

console.log("testing "+obj.success[0].username);

This resulted in the error message: Uncaught TypeError: Cannot read property 'username' of undefined

I have attempted various approaches to resolve this issue but have not succeeded. Any suggestions on where I might be making a mistake would be greatly appreciated.

Thank you

Test it out

obj.success['username']

Remember, objects are not accessed in the same way as arrays. You must specify the key name instead of an index.
