Calculate the distance between two points

JavaScript version
const distance = (p1, p2) => Math.sqrt(Math.pow(p2.x - p1.x, 2) + Math.pow(p2.y - p1.y, 2));
TypeScript version
interface Point {
x: number;
y: number;
}
const distance = (p1: Point, p2: Point): number => Math.sqrt(Math.pow(p2.x - p1.x, 2) + Math.pow(p2.y - p1.y, 2));
