c# to .js

Hi does anyone know how to convert c# into javascript or can create a .js indicator if given a c# code.

It is for the  Linear Regression Forecast indicator in cTrader. I want to use it on my other platform that codes in .js

I also have the mlq4 (mt4) code available if it helps.

Here is the c# code below.

Regards

using cAlgo.API;

namespace cAlgo
{
/// <summary>
/// Linear Regression
/// </summary>
[Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
public class LinearRegression : Indicator
{
[Parameter()]
public DataSeries Source { get; set; }

[Parameter(DefaultValue = 14)]
public int Period { get; set; }

[Output("Main")]
public IndicatorDataSeries Result { get; set; }

public override void Calculate(int index)
{
double sumX = 0, sumY = 0, sumXY = 0, sumXPower = 0;

for (int i = 0; i < Period; i++)
{
sumXPower += i * i;
sumX += i;
sumY += Source[index - i];
sumXY += i * Source[index - i];
}

Result[index] = (sumXPower * sumY - sumX * sumXY) / (sumXPower * Period - sumX * sumX);
}
}
}
