PHP to Javascript - Convert 2 functions and small piece of code.

I have a function for standard deviation and one for simple moving average, doing calculations in php.

I need the javascript equivalent. Obviously function need to be written differently.

My desire is for the same output in Javascript, like php gives.

This is the PHP Code, along with a Javascript function to Display calculated values.

The project task is to produce code that will the calculations. Doesn't matter to me how (with how many function ect.), need same result.

Please note, in the example, php is marked with ///CODE TO MAKE IN JS BEGIN, ///CODE TO MAKE IN JS END.

Bid only if you are able to do it, and do not require any more explanations. Should be straight forward for somebody with experience in JS.

<?php

$period = 7;

$recent = array(13755,13720.9,13738.5,13792.7,13828,13813.1,13854.4);

///CODE TO MAKE IN JS BEGIN

function sd_square($x, $mean) { return pow($x - $mean,2); }

function sma($data, $range)

{

$sum = array_sum(array_slice($data, 0, $range));

$result = array($range - 1 => $sum / $range);

for ($i = $range, $n = count($data); $i != $n; ++$i) {

$result[$i] = $result[$i - 1] + ($data[$i] - $data[$i - $range]) / $range;

}

return $result;

}

$stdev = sqrt(array_sum(array_map("sd_square", $recent, array_fill(0,count($recent), (array_sum($recent) / count($recent)) ) ) ) / (count($recent)-1));$sma = sma($recent,$period);

///CODE TO MAKE IN JS END

?>

<meta charset="utf-8">

<script type="text/javascript">

var recent = [login to view URL]('<?php echo json_encode($recent); ?>');

///CODE TO MADE IN JS BEGIN

///////PROJECT TASK HERE

///CODE TO MAKE IN JS END

var stdev = 13786.085714286;//HARDCODED FOR DEMO , EXPECTING YOUR CODE TO CALCULATE

var sma = 49.458852546719; //HARDCODED FOR DEMO , EXPECTING YOUR CODE TO CALCULATE

function PopulateJs()

{

[login to view URL]("jsstdev").innerHTML = stdev;

[login to view URL]("jssma").innerHTML = sma;

}

</script>

</head>
