Briefly, this happens:
const obj = {}
const map = new Map([['a', obj], ['b', obj]])
const ok = stringify(map)
// "new Map([['a',{}],['b',{}]])"
const bad = stringify(map, null, null, { references: true })
// "(function(){var x=new Map([['a',{}],['b',undefined]]);x[1][1]=x[0][1];return x;}())"
eval(bad)
// Uncaught TypeError: Cannot read property '1' of undefinedThe problem here is that the object type isn't tracked, and therefore isn't taken into account by stringifyPath. The . and [] forms work fine for arrays and objects, but don't for Maps and Sets. The path in those cases is referring to the Array.from() constructions, rather than the resulting objects.
