TypeScript has become the de facto way to build modern web applications. With the rise of design systems and reusable components, building strongly typed polymorphic components is a desirable skill for the modern web engineer. 

This course provides a bottom-up approach to building strongly typed polymorphic components. You will start with a naive implementation of a polymorphic component and explore its drawbacks. You will then use TypeScript to provide a production-ready component interface. Finally, you’ll support advanced use cases with component refs and build a reusable utility you can use on multiple components. 

By the end of the course, you’ll be ready to build components fit for a design system and go beyond basic reusable needs.

Using TypeScript for Building Polymorphic React Components

Let’s learn one more concept before we begin to leverage TypeScript in our polymorphic component solution.


## Getting started
Let’s consider a variant of the `echo` function. We'll call this `echoLength`.
