Greg Price 71596648c2 typing_status: Switch sentinel "recipient" value to `null`. ... This feels a bit more semantically appropriate: it more clearly says "here's some information: there is no (relevant) recipient", rather than "no information available". (Both `null` and `undefined` in JS can have either meaning, but `undefined` especially commonly means the latter.) Concretely, it ensures a bit more explicitness where the value originates: a bare `return;` becomes `return null;`, reflecting the fact that it is returning a quite informative value. Also make the implementation more explicit about what's expected here, replacing truthiness tests with `!== null`. (A bit more idiomatic would be `!= null`, which is equivalent when the value is well-typed and a bit more robust to ill-typing bugs. But lint complains about that version.)		2019-10-24 14:56:56 -07:00
