// Unique Node Map
var nodeMap = new Map();
If node is not in map, add it to map. If it is in map, that means it was seen before and should not be traversed into or cloned
— But, that is a linear check that takes longer the more of an object tree you have traversed
— Yeah..
— Me no likey, but IDK how to do it any other way at the moment... maybe duck typing
— Crazy fun to be able to recreate cycles though
— Check for the list of props in a sorted radix tree would be a good improvement, then if we just don't have that combo of props we know we haven't seen an object
— I could maybe use that string set I was working on before
— Oh yes, perfectly clones objects (almost)
— Why just almost?
— Descriptors aren't copied and only enumerables are copied
— You can look up getters / setters, prototypes, etc
