Why does this simple JSON object throw an error with JSON.parse?

Question

Anyone can probably figure this out. Why does the following JSON object cause a JSON.parse error? It appears to be a valid JSON object. I'm sure I'm doing something completely idiotic in this, the 14th hour of this long workday.

var t = {
    "message": "ok, Heru we go!"
};

JSON.parse(t);

--> syntaxError: Unexpected token o

Many thank yous!

UPDATE

This is the kind of question you ask when you have 2 new puppies and are trying to code on 3 hours of sleep. Please let this serve as a warning for those of you who have come here looking for the same answer- Go to sleep. Give it up. You're worthless today. Try again tomorrow.

"[object Object]" is not valid JSON...

JSON.parse expects a string. The value of t is a javascript object, so it doesn't need to be parsed.

If you had:

var t = "{\"message\":\"ok, Heru we go!\"}";

then JSON.parse would be what you were after.

Don't you want JSON.stringify(t);?

JSON.parse(s); is used to get the object out of a string.

JSON.stringify(t); is used to convert your JSON object to its string equivalent.

YES YES! I can't believe I'm doing this- can you tell I have two new puppies in my house and am getting absolutely no sleep?

t is already a JavaScript object. JSON.parse only works on strings. You could do JSON.parse(JSON.stringify(t)), but that would be kind of pointless.

Thank you! I'm beyond sleep deprived and can't believe I even posted this question. I will not try and delete it as a warning to those of us who try and program on little to no sleep.

The JSON here should be a string. You are passing an object as parameter. Try this

JSON.parse('{ "message": "ok, Heru we go!" }');
