title: Do I always need to call URL.revokeObjectURL() explicitly?
body: <p>I'm using blob to download files, Problem is I want to keep Object URL even after downloading the file, without making major changes in code base.    </p>
  
  <p>So one of the option is not to call <code>URL.revokeObjectURL();</code></p>
  
  <p>Is it safe to depend on browser's garbage collector to avoid any memory leak?</p>
  
  <p>Do I always need to call <code>URL.revokeObjectURL();</code> explicitly ?</p>
