Node.js is Cancer show a wrong way to use nodejs.
But the test code Fibonacci is so funny.
I implement the fibonacci function in other Dynamic Languages for comparison testing.
Languages
Dynamic
- nodejs
- nodejs + cpp module
- python
- pypy: a fast, compliant alternative implementation of the Python language (2.7.1).
- perl
- php
- ruby
- lua
- luajit: a Just-In-Time Compiler for Lua.
Static
If you want to help add more dynamic languagues, please leave the implement code in comments.
Results

lua use local function will get better performance.

Conclusion
nodejs is very FAST.
luajit 2X faster than nodejs, Shocking.
