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.

# Environmental Setup

If you are interested in running this course’s code in an external environment, like in Visual Studio Code, this lesson explains what tools are used to test and run all the code in this course.

# Node version![]()

We’re going to use Node version 16, since that’s the new, long-term support (LTS) version of Node as of June 2022.




# Install `nvm`

We can use [`nvm`](https://github.com/nvm-sh/nvm) to maintain a variety of node versions on a single machine. To install nvm, let’s open a terminal and issue the following command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

After installing, be sure to check your `~/.bash_profile`, `~/.zshrc`, `~/.profile`, or `~/.bashrc`, to ensure the following lines are appended:

Set up an environment with nvm, and install a specific version of Node.
