class SomeClass<T extends string> {
protected someMethod(): void {
}
protected someOtherMethod(): ReturnType<this["someMethod"]> {
// Private or protected member 'someMethod' cannot be accessed on a type parameter.ts(4105)
}
}
Is there any way to reference back the type of protected class member in the class itself?
This can easily solved by using the class name instead of this:
class SomeClass {
protected someMethod(): void {
}
protected someOtherMethod(): ReturnType<SomeClass["someMethod"]> {
}
}
ReturnType<SomeClass<A,B>["someMethod"]>, I'm trying to save that effort

this refers to current class so it allows you to the type from a child class in case it overrides the method, so using direct class name will not allow you make that type dynamic for the children.
