I have a base class and I have inherited the functionality of base class into 3 other classes. Implemented hierarchical inheritance. But now I have to pass the class itself as parameter and print the class name. Any Suggestions?

you mean like this? `Test2.printClassName(Porsche.name);` – Benny Yen Nov 18 '21 at 05:15
@BennyYen But its saying ' error TS2339: Property 'name' does not exist on type 'typeof Porsche'.' – Johanur Rahman Nov 18 '21 at 05:19
or do you mean passing the instance and print its Class name? like this: `Test2.printClassName(new Porsche().constructor.name)` – Benny Yen Nov 18 '21 at 05:19

Yes I need to pass the instance of a class and print its class name – Johanur Rahman Nov 18 '21 at 05:21
I can see its working on stackblitz but whenever I am running it on my IDE (Webstorm) below error is showing error TS2339: Property 'name' does not exist on type 'typeof Porsche'.' – Johanur Rahman Nov 18 '21 at 05:22
that's weird... did you use the `constructor` keyword? `const porsche = new Porsche(); console.log(porsche.constructor.name);` – Benny Yen Nov 18 '21 at 05:29

Yes I have used the `constructor` keyword... Yah it is weird .. Its perfectly working fine on stackblitz but not locally.. – Johanur Rahman Nov 18 '21 at 05:33
It seems it works fine when i run `tsc index.ts --target es6` . But I have already defined the target in tsconfig. Not sure why is it not working when i am running just `tsc index.ts` – Johanur Rahman Nov 18 '21 at 05:57

check out this: [Typescript Documentation](https://www.typescriptlang.org/docs/handbook/compiler-options.html) > # Emit JS for just the index.ts with the compiler defaults `tsc index.ts` – Benny Yen Nov 18 '21 at 06:01
default target is es3 that's why – Benny Yen Nov 18 '21 at 06:02
