TypeScript Named Exports

TypeScript Modules and Namespaces : Exercise-3 with Solution

Write a TypeScript module that exports multiple functions and variables using named exports. Import specific named exports in a separate TypeScript file and use them.

Sample Solution:

TypeScript Code:

main.ts

import { var1, var2, add, greet } from './test_module';

// Use the exported variables and functions
console.log(var1, var2);  
console.log(add(6, 8));  
console.log(greet('Hugleikr Nia')); 

test_module.ts

// Export variables
export const var1 = 'Hello,';
export const var2 = 'TypeScript!';

// Export functions
export function add(a: number, b: number): number {
  return a + b;
}

export function subtract(a: number, b: number): number {
  return a - b;
}

export function greet(name: string): string {
  return `Hello, ${name}!`;
}

Output:

Hello, TypeScript!
14
Hello, Hugleikr Nia!

Run the generated JavaScript file using Node.js:

node main.js
