'Some other value';" to be "Some other value" since I haven't defined "a" but it just throws an "Uncaught ReferenceError: a is not defined". "Is not defined" = undefined right? | |
| Nov 19, 2020 at 7:01 | comment | added | Max Waterman | You could add the way to do this with the [] syntax - from developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… , all of these are possible: obj.val?.prop obj.val?.[expr] obj.arr?.[index] obj.func?.(args) | |

a && a.b && a.c should be a && a.b && a.b.c. I can't edit that in myself because it's not a big enough change for SO to accept and I don't want to do the "change inconsequential things to make it to 6 characters" thing.
