JSON for function argument transfer,

JSON for function argument transfer,

<div dir="ltr">Dear all,
I am 1 month old to web development. just a week before, I got two extremely useful thing in my hand which I am learning now,, (jQuery and JSON)
May be i am wrong , But as per my understanding JSON can be used as argument passer,, for example..
I mean ,, if we have this code
function myFun( x, y ,hedight , width){
 // some code
}
for this we always need to remember the order of arguments,,
but , instead of this can we pass argument with JSON??
like
var myob = {
"y" : 56,
"width" : 60,
"height" : 100,
"x" : 200,
}
function myFun( my_ob){
 // some code
//my_ob.x
//my_ob.y
//my_ob.width
//my_ob.height
//??
}
But I never saw any example with such approach,, Ya i am just 7 day old to JSON, so wanted o have your Guidance..
Also,,, I want to ask,, DO jQuery plugins use this ??<br clear="all">
