Great article!

I think there's a small problem with intermediate values in this code snippet:

  const maxValue = Math.max(...samplingVector)

  samplingVector = samplingVector.map((value) => {
    value = x / maxValue; // Normalize
    value = Math.pow(x, exponent);
    value = x * maxValue; // Denormalize
    return value;
  })

Replace x by value.
