MongoDB plays very well with the rest of the javascript based stack, which mean development and testing is simpler. For many use cases the development time is the real cost, and the database itself is simple enough that what it is running on does not really matter much.

Most people are not building Big Data systems.

Why not rethinkdb or couchdb then ? Mongo is not the only Javascript friendly document oriented database.

Mongo isn't even "Javascript-friendly". It just accepts JSON for queries, that's all. JSON is approximately as related to Javascript as Javascript is related to Java.

Its shell accepts JavaScript commands IIRC. Not sure if that's enough to call it JS Friendly though.

[joepie91_]

It might, but you're not going to be using that shell in an actual application, so that would hardly make a difference. The querying is all JSON.

Every major database does. This is in no way exclusive to MongoDB.

Actually MongoDB is used quite a bit in big data systems.

It has very good integration with Hadoop, Spark etc.
