What in god's name is the point of NodeJS???

Haha BTFO

did i say xml is good/better than json retard?

are there any other data exchange formats?

the better python

There's binary shit like messagepack but it's really just a "better" "faster" json, not fundamentally different.

Are you not sufficiently fed up with using JavaScript on your clients? Well, now you can use it to make all your server infrastructure too!

Nodejs is built on c++ though

And only one single person uses it

Because it is a much simpler language and even less appropriate for serious development. Creating a JIT compiler for Lua was pointless in the first place.
