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

We currently have a `genericSearch` function that can filter properties of type `string` or `number` for any object. However, the disadvantage of this implementation is that it can only search using a single property of an object. An improved generic search would be able to accept one or more properties. For example, if we want to search both the `title` and `description` of our widgets, our call to `genericSearch` might look something like this:





Learn how to extend your generic search function to support searching for multiple object properties simultaneously.
