TypeScript provides a collection of utility types that simplify common type transformations. One such utility is Partial. It is particularly useful when working with React, where components often have props that may or may not be fully defined at all times.

In this article, we will explore the Partial utility type and see how it can be effectively used in a React application. By the end of this article, you will understand how Partial simplifies type definitions and helps create more flexible components.
