A better pattern would be to use Option/Maybe or Either.
If I have something like:
var a = null;
rather than using a?.b I would use:
const a = fromNullable(a);
const aValue = a.map(_ => _.b).getOrElse("No value");
You can further chain like
a.chain(_ => .b) .chain( => .c) .chain( => _.d)
In your anti-corruption layer convert all nulls to Option/Maybe and you don't have to deal with nulls.
I would love to not deal with null/undefined in JS.

I find the ?. really elegant.

But I also find Ruby elegant where things like this are normal.
