The toJSON() method returns a string representation of the Date object.



Return value

A string representation of the given date.


Date instances refer to a specific point in time. Calling toJSON() returns a string (using toISOString()) representing the Date object's value. This method is generally intended to, by default, usefully serialize Date objects during JSON serialization.


Using toJSON()

var jsonDate = (new Date()).toJSON();
var backToDate = new Date(jsonDate);

console.log(jsonDate); //2015-10-26T07:46:36.611Z
