Node.js, Express, jQuery.param() - Remove quotes from JSON

I am serializing a JSON object on the client using jQuery.param():

var test = {"coordinates":[[-122.610168,37.598167],[-122.288818,37.598167],[-122.288818,37.845833],[-122.610168,37.845833],[-122.610168,37.598167]]};

console.log($.param( test ));

After making a GET request, on the server side within an Express route, I access the object with:

console.log('Server received: ' + JSON.stringify(req.query.coordinates));

This outputs the below - note the quotes around each coordinate:

Server received: [["-122.610168","37.598167"],["-122.288818","37.598167"],["-122.288818","37.845833"],["-122.610168","37.845833"],["-122.610168","37.598167"]]

How can I remove the quotes? I can parse to a string and use a regex then parse back to JSON, but that seems inefficient. Can anyone advise what part of the process is adding them and how they can be removed?

Something tells me there's a way to do this in a single, chained function call by using bind, but the best I could come up with was:

var coords = data.map(function(arr){return arr.map(parseFloat);})

This has the benefit of being non-destructive (the original data variable remains intact).

Just try like bellow

var data = [["-122.610168","37.598167"],["-122.288818","37.598167"],["-122.288818","37.845833"],["-122.610168","37.845833"],["-122.610168","37.598167"]]

data.forEach(function(arr){
   arr[0] = +arr[0];
   arr[1] = +arr[1];
})

console.log(data)// prints[[-122.610168,37.598167],[-122.288818,37.598167],[-122.288818,37.845833],[-122.610168,37.845833],[-122.610168,37.598167]]
