The createObjectURL() method creates a DOMString containing a URL representing the object given in the parameter of the method. The new object URL represents the specified File object or Blob object.
Note: The URL lifetime is tied to the document in which it was created.
Syntax:
const url = URL.createObjectURL(object);
Parameters:
- object: A File, image, or any other MediaSource object for which object URL is to be created.
Return value: A DOMString containing an object URL of that object.
Example: In this example, we will create an object URL for the image object using this method.
