What are these coordinates?

Question

satellite navigation

I counted the first function f1();.
Everything is simple here.

let p1 = [-100, 1]; 
  let p2 = [200, 32];

p1= x1 y1
p2= x2 x2
And what are these coordinates of points from 6 numbers? If there are 3 more, then it's understandable x, y, z.
What is it

let p1 = [-100, 1, 5, 4, 3, 15];
  let p2 = [2, 65, 45, 14, 443, 115];

?

// 1) Рассчитать расстояние между точками и вывести в консоль
function f1() {
  let p1 = [-100, 1];
  let p2 = [200, 32];
  let r = getLength(p1, p2);
  console.log("----------------------------------------");
  console.log("-> f1() - Расстояние м/у 2мя точками = " + r);
}

// 2) Рассчитать расстояние между точками и вывести в консоль
function f2() {
  let p1 = [-100, 1, 5, 4, 3, 15];
  let p2 = [2, 65, 45, 14, 443, 115];
  let r = getLength(p1, p2);
}
// =========================================================
function getLength(p1, p2){
  let r = 0;
  let dX = p2[0]-p1[0];
  let dY = p2[1]-p1[1];
  let dis = Math.pow(Math.pow(dX,2) + Math.pow(dY,2),0.5).toFixed(0);
  return dis;
}
// =========================================================
f1();

Answer 1

Just six-dimensional space.

Answer 2

There can be anything, from angles to speeds or regular garbage. Think of it more abstractly, just like an object with 6 parameters, where the first two parameters are the coordinates of this object along the X and Y axes. Here the question is more for you - where do you get p-objects (which are most likely just points, judging by your comments) and why are you getting them? There you will find the answers you need.
Ii.. I'm not a js expert, but is it normal that r is an external variable for a function, but you assign something to it inside the function? In most languages, this construct either won't work or is called a crutch that will shoot you in the leg after n development cycles.
