Test name
Executions per second
Simple
1457070208.0 Ops/sec
Squared comparator
1669224704.0 Ops/sec
Script Preparation code:
pointA = { x: 1, y: 2}; pointB = { x: 10, y: 5}; maxDistance = 4;
Tests:
Simple
Math.sqrt(Math.pow(pointA.x - pointB.x, 2) + Math.pow(pointA.y - pointB.y, 2)) < maxDistance
Squared comparator
(Math.pow(pointA.x - pointB.x, 2) + Math.pow(pointA.y - pointB.y, 2)) < Math.pow(maxDistance, 2)
