Ready to write your very first TypeScript program? In this tutorial, we move beyond configuration and start coding! We’ll show you how to properly set up your `src` folder, create your first `index.ts` file, and use the TypeScript compiler (`tsc`) to transpile your code into working JavaScript.
**In this video, you will learn:**
* How to organize your TypeScript project for scale.
* Writing a simple “Hello World” style program in TypeScript.
* Understanding the relationship between `.ts` and `.js` files.
* Running your project and verifying the output.
