Print JSON parsed object?

You know what JSON stands for? JavaScript Object Notation. It makes a pretty good format for objects.

JSON.stringify(obj) will give you back a string representation of the object.

Most debugger consoles support displaying objects directly. Just use


Depending on your debugger this most likely will display the object in the console as a collapsed tree. You can open the tree and inspect the object.

If you want a pretty, multiline JSON with indentation then you can use JSON.stringify with its 3rd argument:

JSON.stringify(value[, replacer[, space]])

For example:

var obj = {a:1,b:2,c:{d:3, e:4}};JSON.stringify(obj, null, "    ");


JSON.stringify(obj, null, 4);

will give you following result:

"{    "a": 1,    "b": 2,    "c": {        "d": 3,        "e": 4    }}"

In a browser console.log(obj) does even better job, but in a shell console (node.js) it doesn't.
