This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The DOMRectReadOnly() constructor creates a new DOMRectReadOnly object.


var myDOMRectReadOnly = new DOMRectReadOnly(x, y, width, height);


The x coordinate of the DOMRectReadOnly's origin.
The y coordinate of the DOMRectReadOnly's origin.
The width of the DOMRectReadOnly.
The height of the DOMRectReadOnly.


To create a new DOMPoint, you could run a line of code like so:

myDOMRect = new DOMRectReadOnly(0,0,100,100);
// running 'myDOMRect' in the console would then return
// DOMRect { x: 0, y: 0, width: 100, height: 100, top: 0, right: 100, bottom: 100, left: 0 }
