MongoDB Basic operations (script execution with JavaScript shell)

For MongoDB, the View tool has MongoDB vue and so on, the individual is not very accustomed to use the view tool, so prefer to use MongoDB's own JavaScript shell. Not everyone's so-called Ascension B, just personal habits. Some of the content is referenced from the MongoDB authoritative guide 2.

There is a JS script under my bin I can complete the call by executing the command.

MONGO Script1.js
--quiet script1.js [Do not print mongdb shell Version ...]
Load ("Script1.js") is executed after login
