💻 Code

// minimal code for reproduction: Have a class extend another, and have a property with the same name as a generic type
class BaseClass {}

class Item<data> extends BaseClass {
  data: data;
  getData() {
    return this.data;
  }
}

🙁 Actual behavior

TS2339: Property 'data' does not exist on type 'Item'.

🙂 Expected behavior

No transpiler errors

Additional information about the issue

Note: compilerOptions are default

While it may be bad design to have properties and generic types share names, I didn't find it listed anywhere as a breaking change; my mistake if it is :)

Good luck!

Indeed, why it didn't turn up when I filtered by TS2339 in the search bar is beyond my comprehension 👍
