How to Compile a TypeScript Node.js Project
TypeScript is a development tool geared towards making building JavaScript applications more robust. In an application's deployed state (browser or server), TypeScript must be compiled to valid JavaScript. In this lesson, we'll see how the TypeScript compiler provides us with a command to compile and produce JavaScript code from TypeScript.

Though our application is now suited for TypeScript development; to have our code be ready for production, it first must be built (i.e. compiled) as a JavaScript project. This is perfectly ok because TypeScript was only created to help developers during the development phase. Once the app is in production, known bugs should have all been fixed!
To achieve the compiling of our entire TypeScript project, we're going to create a new script in the package.json file which we'll call the build/ script.
