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

The Window.URL property returns an object that provides static methods used for creating and managing object URLs. It can also be called as a constructor to construct URL objects.

Note: This feature is available in Web Workers.

Syntax

Calling a static method:

img.src = URL.createObjectURL(blob);

Constructing a new object:

var url = new URL("../cats/", "https://www.example.com/dogs/");

[2] Implemented under the non-standard name webkitURL.
