Script Preparation code:

var obj = {a: {b: {c: {d: 1}}}}
var badObj = {}

Tests:

Optional Chaining
(obj.a == null ? undefined : obj.a.b == null ? undefined : obj.a.b.c == null ? undefined : obj.a.b.c.d) || 2 (badObj.a == null ? undefined : badObj.a.b == null ? undefined : badObj.a.b.c == null ? undefined : badObj.a.b.c.d) || 2
Lodash
_.get(obj, "a.b.c.d", 2) _.get(badObj, "a.b.c.d", 2)
actual optional chaining
obj?.a?.b?.c?.d || 2 badObj?.a?.b?.c?.d || 2
