JavaScript, Math, Algorithm · Dec 28, 2020
Calculates the distance between two vectors.
- Use
Array.prototype.reduce(),Math.pow()andMath.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
