If you have the mongodb driver installed correctly, this will print out the message ‘Answer: Calling ‘npm install’ with no specific package tells npm to look for ‘package. By fast, we mean that indexes should be in place to satisfy these queries such that we only need to scan the number of documents we are going to return.

Then install the mongodb driver: What is the latency of the longest running operation to the collection, in milliseconds? Here are some URLs that must work when you are done.
One way is to find the lowest homework in code and then update the scores array with the low homework pruned.

Now run the application to get the answer to hw Calling ‘npm install’ with no specific package tells npm to look for ‘package. This homework is meant to give you practice using the “package. You should not need to touch any other code.
With the new schema, this problem is a lot harder and that is sort of the point. Once you have added the indexes to make those pages fast, just validate your homewrok with MongoProc.
