How Can I Convert a JavaScript Object to a String Using JSON.stringify()?

Converting an Object to a String: JSON.stringify to the Rescue

When working with JavaScript objects, often it becomes necessary to convert them into strings for various purposes. However, a simple concatenation with a string (e.g., 'Item: ' o) will result in an uninformative '[object Object]' output.

To overcome this limitation, JSON.stringify() comes to the forefront. JSON (JavaScript Object Notation) is a popular data interchange format. JSON.stringify() serializes an object into a JSON string. This approach provides a rich output, including nested objects and arrays, in a consistent and human-readable format.

For instance, given an object o = {a:1, b:2}, we can convert it to a string using JSON.stringify():

var o = {a:1, b:2};
var jsonString = JSON.stringify(o);
console.log(jsonString);

This will output:

{"a":1,"b":2}

JSON.stringify() is widely supported in modern browsers. However, for legacy browsers, a custom JavaScript implementation can be utilized.
