🕗 Version & Regression Information
- I tested this on version 4.1.2 and nightly. Playground's toolbar was not functioning, so I couldn't check other versions.
⏯ Playground Link
Playground's toolbar was not functioning, so I couldn't check other versions. I reloaded the page a few times and waited for some time, and used different browsers, but it didn't work.
💻 Code
function f<T>() {
const a: T = null!;
const b: T extends string ? T : T = a;
}
🙁 Actual behavior
Gives this error: Type 'T' is not assignable to type 'T extends string ? T : T'. (2322)
🙂 Expected behavior
It should check the type of a
against the two conditional cases and type-check successfully.
