How do i tell javascript to not convert date object to UTC while serializing

Question

I want

JSON.stringify(new Date());

to return local date. How can I do that?

*"and also is there any datatype in javascript for time less date and dateless time ?"* Ask **one** question per question. — T.J. Crowder, Oct 04 '16 at 07:14

@AleksandarMatic Is there any Object/Datatype in javascript for date without time like java.sql.Date — Piyush, Oct 04 '16 at 07:16

The best way to handle this is to write a replacer function and pass that to JSON.stringify. The replacer would detect dates and output the format you want for them.

JSON.stringify(new Date(), function(key, value) {
    var rawValue = this[key];
    if (rawValue instanceof Date) {
        return /*...whatever format you want using `rawValue`...*/;
    }
    return value;
});

There I've made it an inline function, but of course you can make it a named function that you reuse.

Example:

console.log(JSON.stringify(new Date(), function(key, value) {
  var rawValue = this[key];
  if (rawValue instanceof Date) {
    return "Your string here for " + rawValue;
  }
  return value;
}));
