title: Why we add 's' after the name of collection when we want drop that?
body: <p>Here I want to drop my collection(Table in MySQL) but I can't understand why we add 's' to the name of the collection, sample:
  <br>
  [name of Collection(table) : myCollection] 
  <BR></p>
  
  <pre><code>const mongoose = require('mongoose');
   mongoose.connection.collections.myCollections.drop();
  </code></pre>
