Convert JS object to JSON string

Question

If I defined an object in JS with:

var j={\"name\":\"binchen\"};

How can I convert the object to JSON? The output string should be:

Answer 1

In angularJS

angular.toJson(obj, pretty);

obj: Input to be serialized into JSON.

pretty(optional):
If set to true, the JSON output will contain newlines and whitespace. If set to an integer, the JSON output will contain that many spaces per indentation.

(default: 2)
