What is PyExtJs?
Python Extension Packages in Javascript is open-source implementation of some common libraries used
in the scientific python programming.
The main goal of this project is to improve migration of
python language to javascript.

##Performance
This is very important, the test was executed in a MacBookPro i5
The python Code:
import time
import numpy
def test():
x = numpy.array([0.0, 1.0, 2.0, 3.0, 4.0, 5.0])
y = numpy.array([0.0, 0.8, 0.9, 0.1, -0.8, -1.0])
start = time.time()
for num in range(1,10000):
numpy.polyfit(x, y, 3)
end = time.time()
microsecs = end - start
print microsecs * 1000
test()function test() {
x = [0.0, 1.0, 2.0, 3.0, 4.0, 5.0];
y = [0.0, 0.8, 0.9, 0.1, -0.8, -1.0];
var start = +new Date();
for (var i=0;i<10000;i++)
numpy.polyfit(x, y, 3)
var end = +new Date();
var diff = end - start;
alert(diff);
}
test();Python: 1604 milliseconds
Javascript: 14 milliseconds
Javascript! Very fast!!!
