Javascript rect() is used to draw a rectangle.
var c=document.getElementById("myCanvas");
var ctx=c.getContext("2d");
ctx.rect(20,20,150,100);
ctx.stroke();
For this example you need to define <canvas id="ctx" width="300px" height="300px"></canvas>
As output You will see a rextangle.
But it seems, on that site was external js library with custom rect() function..as visph says

Depends on in what output You are looking.
Maybe You just need to wrap rect(5,5,5,5) in alert to see output in browser's alert box:
-> alert( rect(5,5,5,5) )
Or you can wrap it in console.log to see result in a console:
console.log( rect(5,5,5,5) )
All of this should work if Your function returns result value with. like this:
function rect(a,b,c,d) {
var result = a*b*c*d;
// return result to show it in output
return result;
}

Not enough information...
From where come from this function ( or class? ) 'rect' ?
How do you use it exactly, in what context?
If you just execute this ( as you type it in your question ):
rect(5,5,5,5)
... and anything else, obviously you don't get any result.
Or no, you should have errors as result, because rect isn't defined anywhere.

It seems like if you don't have the library which provide this function... :(

@'IceQ' Sergej Kostenko:
I don't know the existence of rect() in JQuery, and don't too have really dived in <canvas> and its js specifities, so no more know rect() in js ^^
I was just supposed an arbitrary library with an arbitrary 'rect' identifier :D

Once I took JavaScripting on a different website, and it taught me the shape drawing thingy, all you do is rect(x Size, y Size, x Position, y Position) as I remember it. It is used to create a rectangle. I am using it inside a function if that will help...
