Your example isn't making sense to me. Nodejs and MongoDB are excellent tools. There's a reason they're some of the most commonly possessed and used tools world-wide.

We could continue this all day. I can tell you're very inexperienced in saying specifically that a tool is bad. You'll learn as you grow in experience that even if you don't like a tool, that it can be useful for lots of other people in lots of circumstances. It may seem unbelievable to you, but when you get some more notches on your belt, you'll understand what I'm saying. Good luck!
