    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()
    

    The Javascript Code:
    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!!!
