The toArray() method returns an array that contains all the documents from a cursor. The method iterates completely the cursor, loading all the documents into RAM and exhausting the cursor.

Returns:An array of documents.

Consider the following example that applies toArray() to the cursor returned from the find() method:

var allProductsArray = db.products.find().toArray();

if (allProductsArray.length > 0) { printjson (allProductsArray[0]); }

The variable allProductsArray holds the array of documents returned by toArray().
