Error occurs when JSON.parse is used

<!DOCTYPE html>

<html>
<head>
    <title></title>
</head>
<body>
    <script>        
        var data = "{ 'name': 'John' }";
        var result = JSON.parse(data);
    </script>   
</body>
</html>

When trying to parse the JSON string in the provided code, an error occurs at the second variable declaration. Why does this happen? (Chrome might display "unexpected token ILLEGAL", while Firefox could show "JSON.parse")

Answer №1

Always remember to utilize double quotes instead of single quotes:

 let sentence = "{ 'hello': 'world' }";
 let data = JSON.parse(sentence); 
 data["hello"]

Answer №2

Personally, I found it more convenient to convert the object into a string using String() prior to utilizing JSON.parse()

var savedObject = localStorage.bar;
var decoded = JSON.parse(String(savedObject));
