The biggest problem is dealing with callbacks (and yes even promises use callbacks , and generators need to be wrapped in a cor-routine framework in order to work as cor-routines ). I want to write a quick script doing some busy work , I now have to think about synchronicity even though the script does not need to be non blocking. Of course in these circumstances, I want to move back to Ruby or Python, which actually let me code the thing I want to code without forcing callbacks on me. So when you have to do 20 i/o operations in sequence, using nodejs becomes really tedious.
