💻 Code
type Type<T> = new (...args: any[]) => T;
function inject<T>(t: Type<T>): T;
function inject(t: any): any; // comment out this line => the type of `c2` will be `ClassWithCtorArgs`
function inject(t: any): any {
return t;
}
class Class {}
class ClassWithCtorArgs {
constructor(x: number) {}
}
// type: Class ✅
const c1 = inject(Class);
// type: any ❌
const c2 = inject(ClassWithCtorArgs);🙁 Actual behavior
The type of c2 constant from the example is any.
🙂 Expected behavior
The type of c2 constant from the example should be ClassWithCtorArgs.
