Use either as appropriate. Happens to the best of us ;)

You can execute Java Script in Mongo CLI or command prompt The print() method simply prints the data arguments that are passed into it. print("Hello From Mongo");

eg:

print(data, ...);
printjson(object);
print(JSON.stringify(object));

The printjson() method prints a pretty form of the JavaScript object. The print(JSON.stringify(object)) method also prints a tightly compact string form of a JavaScript object.
