The difference is the language/standard in question neither originated with NodeJS nor is NodeJS now nor has it ever been led by the people behind the language/standard (unlike Python)...

When you hear "NodeJS", you really need to bethinking of it in the same category as IE (wrt browser behavior) or Visual C/C++. It's but one, often (knowingly/deliberately) quirky, non-standard implementation by a group that doesn't necessarily have your best interests at heart or the interests of those outside their own platform umbrella.
