This method is especially helpful for dynamically generated file URLs. Sometimes, you may want to save programmatically generated data as a file using JavaScript. That's where blobs and object URLs are useful. A Blob object is a file-like object used to represent raw immutable data. Blob objects contain information about the type and size of data they store, making them very useful for storing dynamic contents in the browser.

This method is helpful to create an object URL that represents a blob or a file. The browser will release all object URLs when the document is closed or reloaded. However, it is a good practice to release object URLs whenever they are no longer required to improve performance and minimize memory usage.
