title: Delete all documents in MongoDB collections in Mongo shell
body: <p>I would like to delete all documents in all MongoDB collections. Is there a way to delete all documents in all collections.</p>
  
  <p>I was using <code>db.collection.remove({})</code> but it only removes all documents in one collection. Is there any command to do? I'm using NodeJS mostly, maybe there is a chance to use NodeJS to delete all documents in all collections?</p>
  
  <p>Sorry if the question is dumb, just started working in MongoDB.</p>
