Hi. Before I ask question, thank you for this project.
I just wanted to learn typescript. That's why I chose your project. This Project is awesome. I was able to learn both styles how to handle functional component and class component. when i using class component. has got error about "Parsing error: Unexpected reserved word 'public'." like readonly, public... etc...
I thought problem is in .eslintrc.js or tsconfig.json. but I couldn't figure it out.
So If you don't mind, give me some advice.

here is my code.

//////////////////////////////////////////////////////////////////////////////////////////////////////////

User.ts

export class User implements IUser {
  id: string = cuid();
  get fullName(): string {
    return `${this.firstName} ${this.lastName}`;
  }

  constructor(public firstName: string, public lastName: string) {} <<<<<<<<<<<<<<< i've got error here(public)

  static deserialize(dto: IUserDTO): IUser {
    const model = new User(dto.first_name, dto.last_name);
    model.id = dto.id;

    return model;
  }

  serialize(): IUserDTO {
    return {
      id: this.id,
      first_name: this.firstName,
      last_name: this.lastName,
    };
  }
}

ClassCounter.tsx

export default class ClassCounter extends React.Component<Props, State> {
  state: State = {                 <<<<<<<<<<<<<<<<<< and i couldn't write readonly reserved keyword. cuz faced parsing.error
    count: 0,
  };

  handleIncrement = () => {
    this.setState({ count: this.state.count + 1 });
  };

  render() {
    const { handleIncrement } = this;
    const { label } = this.props;
    const { count } = this.state;
    return (
      <div>
        <span>
          {label}: {count}
        </span>
        <button type="button" onClick={handleIncrement}>
          {`Increment`}
        </button>
      </div>
    );
  }
}
