How to use Switch Statement Inside a React Component?

When the switch statement is used within a React component it can greatly improve the readability and structure of the code. The logic of a switch statement can be clear and concise. This avoids complex and difficult nested if-else blocks.

This leads to more maintainable and better-organized code. In large projects it is necessary.

Steps to Create React App

Step 1: You will start a new project using the following command
