Watch how far you generalize that view. I realize that "I can do everything with a single...language" can make "everything" mean anything. I had a coworker that helped a middle eastern country with security software. He went full Javascript on it: Node, Mongo, etc. It worked. JS did everything. While he didn't go into details, afterwards he thought it was a bad idea. A great learning experience on when to define "everything" properly as well as what is outside of it.

Yes I totally agree that like most "rules on software" there is the need to be judicious enough to know when to follow the rule is not a good idea... However I more often see the contrary, of adding a multitude of systems together without very strong reasons.

just wondering why Mongo is considered a part of "JS". Is it because of the MEAN stack?

[virmundi]

Part of it is JSON as the storage format. Another part is its Node driver. The whole API fit it well. It understood async programming. It felt JS-like. The input and output were JSON instances. Finally, yea, from what I know of him "web scale" did play part in the decision. Oh those heady days.

For data that's mostly to do with the the API provided by the particular mongodb driver, than mongodb itself. Mongo stores and transmits BSON, not JSON. Most mongo drivers expose an API that serialises your data to BSON for writes and wraps the BSON data with a JSON-like interface for reads.

postgresql has the jsonb column type which is just as powerful as mongo

Possibly because of JSON as the storage format.

Because of JSON and "web scale".
