How Can I Convert a JavaScript Object to a Readable String?

Converting an Object to a String in JavaScript

Many times while working with JavaScript objects, we want to convert them into strings so that we can print them, send them over the network, or store them in a file. This can be done using the toString() method, but the output is not very readable.

Consider the following example:

var o = {a:1, b:2}
console.log(o)
console.log('Item: ' + o)

This will output:

Object { a=1, b=2} // very nice readable output :)
Item: [object Object] // no idea what's inside :(

As you can see, the object is displayed as [object Object], which is not very informative.

To get a more readable string representation of the object, we can use the JSON.stringify() method. This method converts the object to a JSON string, which is a human-readable representation of the object.

Here is the code using JSON.stringify():

var obj = {
  name: 'myObj'
};

JSON.stringify(obj);

This will output the following string:

"{name: 'myObj'}"

Now the string representation of the object is much more readable.

JSON.stringify() is supported by all modern browsers. However, if you are supporting older browsers, you may need to include a JS version of JSON.stringify().
