Then, to remove an edge, let's do the inverse and splice them out of each others' lists.

xxxxxxxxxx
 
removeEdge(src, dest) {
  const srcDestIdx = this.adjacencyList.get(src).indexOf(dest);
  this.adjacencyList.get(src).splice(srcDestIdx, 1);
​
  const destSrcIdx = this.adjacencyList.get(dest).indexOf(src);
  this.adjacencyList.get(dest).splice(destSrcIdx, 1);
}
