Euclidean distance
JavaScript, Math, Algorithm · Dec 28, 2020

Calculates the distance between two points in any number of dimensions.
- Use
Object.keys()
andArray.prototype.map()
to map each coordinate to its difference between the two points. - Use
Math.hypot()
to calculate the Euclidean distance between the two points.
const euclideanDistance = (a, b) =>
Math.hypot(...Object.keys(a).map(k => b[k] - a[k]));
euclideanDistance([1, 1], [2, 3]); // ~2.2361
euclideanDistance([1, 1, 1], [2, 3, 2]); // ~2.4495
