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

Now we’ll create a new React component to style our `IPerson` data type, like we did with `IWidgets`. We’ll also make use of a few Unicode emojis to improve the overall display of the properties, adding a 👤 symbol next to the name and a 🎂 beside the birthday.

# Formatting Dates

To easily format each person’s birthday, we’ll use the built-in JavaScript function `toLocaleDateString()`. The `toLocaleDateString()` function can take optional locale and settings parameters, but when these are not provided, the function uses location of the user’s browser to format the date. This is often a good option for client-facing apps that potentially has users all around the world. Here’s an example of how to use `toLocaleDateString`:
