Javascript JSON string to object

Question

When I query a database, I receive a string as follows:

{
 S: '[{"firstName":"Max","lastName":"Mustermann","age":40},{"firstName":"Hagbard","lastName":"Celine","age":44},{"firstName":"Karl","lastName":"Koch","age":42}]'
}

How can I go about converting the string above to JSON objects to receive something like this:

var someData = [
 {firstName: "Max", lastName: "Mustermann", age: 40},
 {firstName: "Hagbard", lastName: "Celine", age: 44},
 {firstName: "Karl", lastName: "Koch", age: 42},
];

Would appreciate any assistance at all, thank you very much!

• Daniel A. White: have you tried someData = JSON.parse(someObj.s)?
• webcoder: you can use JSON.parse(yourdata)
• Deep: Hi, when I use that I get Error [SyntaxError]: Unexpected token o in JSON at position 1
• Halmon: First JSON.stringify(someData) and then parse it. Seems like you're already passing a string version of a JSON object
• Deep: @Halmon Yes, I wanted to convert that string version back to a JSON object but seem to be getting Error [SyntaxError]: Unexpected token o in JSON at position 1 while using JSON.parse(yourdata)

Answer 1

const receivedFromDB = {
 S: '[{"firstName":"Max","lastName":"Mustermann","age":40},{"firstName":"Hagbard","lastName":"Celine","age":44},{"firstName":"Karl","lastName":"Koch","age":42}]'
};
const arrayOfData = JSON.parse(receivedFromDB.S);
console.log(arrayOfData);

• Deep: Thank you very much! Works perfect, I was missing the '.S'. I am waiting to accept your answer in 2 mins time :)
