This @Conaclos 's suggestion is good to add.
ref: #395 (comment)
Suggested change
| /// Typescript variable declaration without any `type` or `initialization` can cause issue later in the code. | |
| /// TypeScript variable declaration without any type annotation and initialization have the `any` type. | |
| /// The any type in TypeScript is a dangerous “escape hatch” from the type system. | |
| /// Using any disables many type checking rules and is generally best used only as a last resort or when prototyping code. | |
| /// TypeScript’s `--noImplicitAny` compiler option doesn't report this case. |
After fixing this, you need to run just codegen again 🙏

@TaKO8Ki Thanks for completing it! We can merge this after updating above suggestion. |

I have taken over #395. Thank you for the work @b4s36t4.
Test Plan
All existing tests should pass. #395 has added some test cases for valid and invalid situation and I've improved them.
In addition, I have corrected all the issues pointed out in #395 for now.
