Tests:

Optional chaining after transpiling
iterations.forEach(function () { var _a, _a$b, _a2, _a2$b; var aa = (_a = a) === null || _a === void 0 ? void 0 : (_a$b = _a.b) === null || _a$b === void 0 ? void 0 : _a$b.c; var bb = (_a2 = a) === null || _a2 === void 0 ? void 0 : (_a2$b = _a2.b) === null || _a2$b === void 0 ? void 0 : _a2$b.d; });
R.path
iterations.forEach(function () { var aa = R.path(['b', 'c'])(a); var bb = R.path(['b', 'd'])(a); });
