I am using JSON.stringify() on html <input>s to send through a websocket like so:

JSON.stringify({
    numberValue: $('#numberValue').val()
})

but it encodes $('#numberValue').val() as a String.

How can it be encoded as a Number?

Convert it to an integer first.

JSON.stringify({
    numberValue: parseInt($('#numberValue').val(), 10);
})
