How do I use module exports in TypeScript?

In TypeScript, you can use module.exports to export functions, objects, or variables from a module. For example:

// myModule.ts
const myFunction = () => {
    console.log('Hello from myFunction!');
};

module.exports = myFunction;

Can I export multiple things from a single file?

Yes, you can export multiple items using an object. For example:

// myModule.ts
const myFunction = () => {...};
const myVariable = 42;

module.exports = { myFunction, myVariable };

How do I import these exports in another file?

You can import the exports using require. For example:

// anotherFile.ts
const { myFunction, myVariable } = require('./myModule');
myFunction(); // Calls the function
console.log(myVariable); // Logs 42

Are there any differences when using ES modules?

Yes, with ES modules, you would use export and import syntax instead. For example:

// myModule.ts
export const myFunction = () => {...};
export const myVariable = 42;

And import it like this:

import { myFunction, myVariable } from './myModule';
