I have recently done something similar to this using the
"Haversine Formula" on WGS-84 data, which is a derivative of the "Law of Haversines" with very satisfying results.
Yes, WGS-84 assumes the Earth is an ellipsoid, but I believe you only get about a 0.5% average error using an approach...

What is the fastest or most elegant way to compute a set difference using Javascript arrays?

A = [1, 2, 3, 4];
B = [1, 3, 4, 7];
diff = A.filter(function(x) { return B.indexOf(x) < 0 })
console.log(diff);

diff = A.filter(x => !B.includes(x) );
console.log(diff);
