TypeScript’s generics are a powerful tool that enables developers to ensure their code is flexible and reusable. Using generics can help developers manage exactly what types are used in functions and components around the application.

In this course, we’ll first get an overview of TypeScript generics and create generic search and sort functions. Next, we’ll create a React component for searching that would leverage our generic search function. Then, we’ll create a generic function and a React component for sorting and filtering, respectively. Finally, we’ll bring all these functionalities together to create one component that can manage searching, sorting, and filtering of any data passed to it.

By the end of this course, you'll know how to write generic TypeScript functions and craft React components that use TypeScript generics. You’ll also be able to deploy concise solutions in both business logic and user interface senses for searching, sorting, and filtering data on client side in applications.

Building User Interfaces and Functions with TypeScript and React

It’s time to render more than just the title and description properties of our IWidget type. Let’s make a new component, WidgetRenderer. Unlike the previous components we’ve seen, WidgetRenderer will accept the IWidget type directly as its property type. This way, we can use **#key# spread syntax: Allows an iterable such as an array expression or string to be expanded in places where zero or more arguments are to be used. #key#** to pass in each widget directly.


## Unstyled rendering of all `widget` properties

First, let’s render all properties of our widgets, each within a `<p>` tag.
