Run JavaScript code from Python.

PyExecJS is a porting of ExecJS from Ruby.
PyExecJS automatically picks the best runtime available to evaluate your JavaScript program,
then returns the result to you as a Python object.

A short example:

>>> import execjs
>>> execjs.eval("'red yellow blue'.split(' ')")
['red', 'yellow', 'blue']
>>> ctx = execjs.compile("""
...     function add(x, y) {
...         return x + y;
...     }
... """)
>>> ctx.call("add", 1, 2)
