Step 1: Basic Functional Component

Create a Message component that takes a text prop and displays it inside a <p> element.

// Message.js
import React from "react";

const Message = (props) => {
  return <p>{props.text}</p>;

Step 1: Basic Types

In TypeScript, basic types like number, string, and boolean can be explicitly declared.

const a: number = 0;

Step 2: Arrays and Type Checking in Functions

This task involves creating a function with typed parameters and testing the behavior when the wrong type is passed.
