💻 Code

Promise.resolve(true)
	.then(result => result && Promise.resolve("hello"))
	.then(something => console.log(something));

🙁 Actual behavior

Got a compilation error:

    Argument of type '(result: boolean) => false | Promise<string>' is not assignable to parameter of type '(value: boolean) => string | PromiseLike<string>'. Type 'false | Promise<string>' is not assignable to type 'string | PromiseLike<string>'. Type 'boolean' is not assignable to type 'string | PromiseLike<string>'.

And something was inferred as boolean.

🙂 Expected behavior

No compilation error and something should have been inferred as boolean | string.
