Solution

Here is a step-by-step guide on how to write the class as per your requirements in TypeScript:

  1. First, we need to define the interfaces for the constructor and the class. The constructor interface will have firstName and lastName properties. The class interface will have workOnHomework and displayName methods.
interface IStudentConstructor {
  firstName: string;
  lastName: string;
}

interface IStudentClass {
  workOnHomework(): string;
  displayName(): string;
}
  1. Now, we can define the StudentClass that implements the IStudentClass interface. The constructor of this class will accept firstName and lastName as arguments.
class StudentClass implements IStudentClass {
  constructor(private student: IStudentConstructor) {}

  workOnHomework(): string {
    return "Currently working";
  }

  displayName(): string {
    return this.student.firstName;
  }
}
  1. Now, you can create an instance of StudentClass and call its methods.
const student = new StudentClass({ firstName: 'John', lastName: 'Doe' });
console.log(student.workOnHomework()); // Outputs: Currently working
console.log(student.displayName()); // Outputs: John
  1. To ensure that there are no TypeScript errors, you can run npm run build. If there are no errors, the code is correctly written.

Remember, every variable in TypeScript should have a type. In this case, firstName and lastName are of type string, and the methods workOnHomework and displayName return a string.
