thanks for your efforts, could you take a look at multi level sorting that you recently upgraded to Node 18 ?

when you use assert.deepEqual() you almost always need chai.config.truncateThreshold = 0; (also for strictEqual() on long-ish strings). currently the test's output looks like this:

expected undefined to deeply equal [ { name: 'gisela', …(5) }, …(16) ]

which makes it hard to debug. also, the random tests generate records that are missing certain keys, but i dont know whether you wrote them, as the fork has no diff.

(I would have posted this on the fork, but I get the good old "Comment Owners is invalid" error ...)

When using Math.hypot(dx, dy) tests succeed. When using Math.sqrt(dx*dx + dy*dy) one static test fails. I have not looked into rounding intermediate results to six figures after the decimal point.

I do think you should specify in the description spaces should be taken out.

I haven't thought hard enough about how and why Math.hypot and Math.sqrt differ, and how to solve that. But fixing that somehow, if possible, would probably be a good thing.

I'll improve later ;-)

Description update ;-) Something more clear: Do not calculate the distance with the spaces; rounding to 6 decimal place when compare distance.

But I don't know why If I take the spaces out the static tests fail. Math.hypot(dx, dy) and Math.sqrt(dxdx + dydy) should got same result, isn't it?(I'm not test for it, perhaps later ;-))

I absolutely agree. It should work.

Also, world peace and free beer .. :P

I'm a little busy right now, I will have a test later. I guess it's because I didn't calculate the distance to the space.

[ [ '38.854893', 'I' ],
  [ '39.732833', 'F' ],
  [ '35.441404', 'A' ],
  [ '28.575290', 'D' ],
  [ '28.127003', 'E' ],
  [ '28.771395', 'H' ],
  [ '29.699757', 'B' ],
  [ '28.991322', 'G' ],
  [ '36.767667', 'C' ] ]

In my calculations, all the numerical values are almost half of the difference. I guess you calculate space as 1. And based on my true intentions, the spaces are not calculated from the distance. That is: From one point to the next, the distance is 1. For example:

. . . .
. A B .
. C . .
. . . .

In this matrix, the distance from A to C is 1, right? So, the distance from A to B is 1 too. Do you understand?

But it's really a bug in my description, because it's not clear. So I'll fix my description ;-)

Description update ;-)
