title: Why is the MongoDB constant in index.js not required when using Mongoose?
body: <p>As an aspiring developer, I was watching a video about mongoose on YouTube and noticed that the developer removed the MongoDB constant variable requiring MongoDB and just created one for Mongoose.</p>
  
  <p>They say its an object modeling tool so if it's a tool for MongoDB shouldn't the MongoDB variable still be required in the file with the variables and routers? </p>
  
  <p>I will admit I don't have good backend knowledge as a beginner so if you can explain in layman's terms that would be great.</p>
