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)
