If you’re looking to move beyond vanilla JavaScript and take your skills to the next level, then you’ve come to the right place. TypeScript is an in-demand language that sits on top of JavaScript. This means you can do everything you can in JavaScript with TypeScript, but also enjoy countless other perks including support for JS libraries, NPM, static typing, and much more.

In this course, you’ll start from the beginning and work your way up to more advanced concepts like type checking, iterators, and manipulating objects and arrays. You'll get a chance to get your hands dirty with plenty of real practice along the way.

For JavaScript developers, TypeScript is a must-know language, not only for today but also for years to come. Don't miss out.

## What is an import shortcut?
TypeScript’s configuration can create shortcuts to specific areas of the code. A shortcut can be useful in a situation where many imports are deep in another branch of the code which requires a lot of navigating; for example `/../../../../...`. 

## Configuration
To set up a shortcut, TypeScript’s configuration **must** have a `baseUrl` in the `tsconfig.json`. Then, it’s possible to add many shortcuts. Each of the shortcuts go in the `paths` list and are relative to the `baseUrl`. The definition of each path contained is a keys-values list, for which the key is the pattern to look for when importing and the value is the location to look for in the actual TypeScript file. 

The configuration can look like the following:
