# Before you start

VS Code contains many navigation and refactoring tools that enable you to move around your code with the greatest of ease.&#x20;

In this exercise, you'll learn how to format, move, duplicate, delete, fold, extract, find, browse, rename, peek, extract and even how to trick the TypeScript parser into checking your JavaScript for errors.

Make sure that you run `npm install` on the "start" project **before** you being this exercise.
