What is the best way to structure a TypeScript module?

A well-structured TypeScript module typically includes clear separation of concerns, using interfaces and classes to define types, and organizing related functions and variables together. You should also consider using namespaces or modules to encapsulate your code.

Can you give me an example of a simple TypeScript module?

Sure! Here's a simple example:

// mathUtils.ts
export function add(a: number, b: number): number {
    return a + b;
}

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

This module exports two functions, add and subtract, which can be imported and used in other files.

How do I import this module in another file?

You can import the module like this:

import { add, subtract } from './mathUtils';

console.log(add(5, 3)); // Outputs: 8
console.log(subtract(5, 3)); // Outputs: 2

What are some best practices for organizing TypeScript modules?

Some best practices include:

1. Group related functionalities together.
2. Use index files to re-export modules for easier imports.
3. Keep your modules small and focused on a single responsibility.
