TypeScript Exporting Classes

TypeScript Modules and Namespaces : Exercise-2 with Solution

Write a TypeScript module that exports a class called Student with properties name and age. Import the Student class in another TypeScript file, create instances of Student, and display their information.

Sample Solution:

TypeScript Code:

main.ts

import {Student} from './student';

// Create instances of Student
const student1 = new Student('Doris Mauri', 18);
const student2 = new Student('Joel Darinka', 20);

// Display student information
student1.displayInfo();
student2.displayInfo();

student.ts

export class Student {
  constructor(public name: string, public age: number) {}

  displayInfo() {
    console.log(`Name: ${this.name}, Age: ${this.age}`);
  }
}

Explanations:

The above code imports the "Student" class from the "student.ts" module, creates two instances of 'Student', and displays their information in the console.

Output:

Name: Doris Mauri, Age: 18
Name: Joel Darinka, Age: 20
