This code creates many new arrays and one new closure each time it runs, which could degrade performance as all of those things need to be garbage collected.
I would suggest the following refactoring:
const u = path[0];
const v = path[1];
if (hasEdge(u, v)) {
removedEdges.push({ u, v, weight: getEdgeWeight(u, v) });
removeEdge(u, v);
}
if (hasEdge(v, u)) {
removedEdges.push({ u: v, v: u, weight: getEdgeWeight(v, u) });
removeEdge(v, u);
}

| return arr.includes(item); |

I bet it's possible to add proper types here.
