Transforming a JavaScript array into a JSON format

Is there a way to convert a JavaScript array into JSON format?

[{
    "userName": "Rodrigo",
    "date": "April 25, 2017",
    "score": 5
}]
[{
    "userName": "Jon",
    "date": "April 24, 2016",
    "score": 4
}]

Error: There is a parser error on line 5

This is my code snippet

var result = [];
var allInfo = {
    userName,
    date,
    score
 };
 result[i] = allInfo;
 return JSON.stringify(result);

Answer №1

If the example given is considered invalid and you need to convert a JavaScript object to JSON, you can use the JSON.stringify() method.

var data = [{
    "name": "Alice",
    "date": "May 12, 2018",
    "result": 9
}, {
    "name": "Bob",
    "date": "April 30, 2019",
    "result": 7
}];

console.log(JSON.stringify(data));
