Fixed accidental possibility to create `Infinity`/`-Infinity` number literal types by Andarist · Pull Request #56301 · microsoft/TypeScript

Andarist · 2023-11-03T08:45:29Z

While there are some issues open about allowing those in some form, I think that - for the time being - the fact that they can be constructed (somewhat) should be considered a bug.

…literal 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/158562/artifacts?artifactName=tgz&fileId=9871919655992580B3C2C5C2A0869800491FAAC90E99AFFD7550D5FCCA784BAE02&fileName=/typescript-5.4.0-insiders.20231113.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@5.4.0-pr-56301-7".;

@jakebailey Here are the results of running the user test suite comparing main and refs/pull/56301/merge:

There were infrastructure failures potentially unrelated to your change:

2 instances of "Package install failed"

Otherwise...

Something interesting changed - please have a look.
