How to calculate the Euclidean distance between two points in JavaScript

Answer 1

// The Euclidean distance is a measure of the straight-line distance 
// between two points in a 2D or 3D space

function CalculateEuclideanDistance(x1, y1, x2, y2) {
  // Calculate Euclidean distance between two 2D points
  return Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2));
}

const x1 = 3.0, y1 = 4.0;
const x2 = 5.0, y2 = 9.0;

const distance = CalculateEuclideanDistance(x1, y1, x2, y2);
console.log(`Euclidean Distance: ${distance.toFixed(5)}`);
