From my experience, the easiest and most widely used approach to javascript convert object to string is using JSON.stringify(). It’s both simple and readable:
var o = { a: 1, b: 2 };
console.log('Item: ' + JSON.stringify(o)); // Output: Item: {"a":1,"b":2}
This method gives you a clean, human-readable string representation of your object, which is perfect for logging or debugging. If you need to make the output easier to read with some indentation, you can also pretty-print the string:
console.log(JSON.stringify(o, null, 2)); // Pretty-printed format
This can make things more readable when you’re working with larger objects.
