Some Python Functions For Javascript.

PythonForJS.js

/*
A script of the programmers who have used PYTHON and are now wsing JAVASCRIPT
This script has some of the built-in function in python as the javascript functions
that will make you feel easier with JAVASCRIPT.

Available Functions:
  1. str(value)
  2. int(value)
  3. sum(iretable_list)
  4. max(*args)
  5. min(*args)
  6. abs(number)
  7. len(array_or_string)
  8. format(text, format_specs)
  9. zip(Arrays)
  10. round(number)

--All functions are made just to resemble the functions in python
--some may or may not work in the same way as the python's function does
--so if you can please modify it and reply the modifications at: [email protected]
