What method should be used to retrieve all documents from a cursor using mongosh?

The correct method to retrieve all documents from a cursor in mongosh is to use db.inventory.find().toArray(). This method combines two important concepts in MongoDB: the find() method and the toArray() function.

The find() method is used to query documents from a collection – in this case, inventory. By default, find() returns a cursor, which is an object that allows iteration over the documents fetched from the database. This cursor does not hold the actual documents; instead, it allows you to step through the results one at a time.

After obtaining the cursor from find(), the toArray() method is called. This method converts the cursor into an array format, fetching all the documents in one operation and returning them as an array. This is particularly useful for manipulating or reading the results when you want all documents to be available at once, rather than iterating through them one at a time.

In summary, using db.inventory.find().toArray() effectively retrieves all documents from the inventory collection by first querying them and then converting the results into an array format, making them easy to work with.
