💻 Code

}
precise: A
}
function sparrow(): boolean {
const sobbed: boolean = true;
return "abc" < (sobbed ? new Pantries<string>("a") : new Pantries<string>("b") ).precise;
}
function sparrow1(): string {
const sobbed: boolean = true;
return (sobbed ? new Pantries<string>("a") : new Pantries<string>("b") ).precise;
}
function sparrow2(): boolean {
const sobbed: boolean = true;
return "abc" < (sobbed ? (new Pantries<string>("a")) : new Pantries<string>("b") ).precise;
}
🙁 Actual behavior
There was a problem when parsing the sparrow method, while the other methods worked fine.
🙂 Expected behavior
There will be no error reports or clear prompts
