Calculates the distance between two vectors.

  • Use Array.prototype.reduce(), Math.pow() and Math.sqrt() to calculate the Euclidean distance between two vectors.
const vectorDistance = (x, y) =>
  Math.sqrt(x.reduce((acc, val, i) => acc + Math.pow(val - y[i], 2), 0));
vectorDistance([10, 0, 5], [20, 0, 10]); // 11.180339887498949
