title: How to import an external javascript library in a typescript project
body: <p>I want to create a small library as an excuse to learn Typescript, but what happens is that I really am not able to import a Javascript library (node-json-equal) to my typescript project. I didn't find a lot on internet that explain clearly how it works, so I bet you to explain me how to solve the problem properly and why is my approach incorrect... well I guess because properly that external library isn't typed.</p>
