Remove nonNullUnknownType #57665

jakebailey · 2024-03-06T19:21:26Z

As far as I can tell (and test), this unknown variant is no longer needed. Probably due to the changes to how unknown is more or less {} | undefined | null.

This effectively finishes reverting #45575; most of it was removed in #49119 (as expected). By the numbers, #45575 added the declaration of and 5 uses of nonNullUnknownType, #49119 removed 3 references, and this PR removes the 2 remaining references and declaration.

Oh no - I hope it's not distributive like boolean 👀

Oh no - I hope it's not distributive like boolean 👀

It's not :D although internally such a type kinda exists (unknownUnionType) - I don't think it's particularly special though, it's just a literal internal creation of a union that contains those 3 types

Hey @jakebailey, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/160449/artifacts?artifactName=tgz&fileId=EBAF0A0102E43BF68F69F9828C9B1C0EA5D2370B5487E56CA4D2969AA0AEE1CD02&fileName=/typescript-5.5.0-insiders.20240315.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/pr-build@5.5.0-pr-57665-10".;
