- select the contributor at the end of the page -
Sure JavaScript might not directly support the concept of interfaces, but in TypeScript not only can you create and use interfaces but you can also extend them.  In this video excerpt from Dan Wahlin and John Papa's new course TypeScript Fundamentals you'll see how to use interface extensions to clean up the constructor of your TypeScript classes.  In the full course Dan and John show various tooling and framework options available, static typing, and how to create and use modules.
