TypeScript Transpiler with Babel

in

So basically, you write your code in TypeScript (which is like JavaScript but with extra features), and then this magical tool called Babel transforms it into regular old JavaScript that can be run by any browser or server.

Here’s an example: let’s say you have a file named `my-component.ts` that looks something like this:

// my-component.ts
import React from 'react'; // Importing React library

interface Props { // Defining interface for props
  name: string; // Name prop with type string
}

const MyComponent = (props: Props) => { // Defining MyComponent function with props parameter of type Props
  return <div>Hello, {props.name}</div>; // Returning a div element with a greeting and the name prop
};

export default MyComponent; // Exporting MyComponent function as default

This code defines a React component called `MyComponent`, which takes in a prop named “name” and returns some HTML that includes the value of that prop. Now let’s say you want to use this component on another page, but your other page is written in plain old JavaScript (not TypeScript). No problem! You can still import it using Babel:

// my-other-page.js
// Importing the React library to use its functionalities
import React from 'react';
// Importing the MyComponent component from the my-component.js file
import MyComponent from './my-component';

// Defining a function called App that returns some HTML
const App = () => {
  return (
    // Creating a div element with a heading and a MyComponent component
    <div>
      <h1>Hello, world!</h1>
      <MyComponent name="John Doe" />
    </div>
  );
};

// Exporting the App function to be used in other files
export default App;

So basically, what’s happening here is that when you run your code through Babel (which can be done using various tools like `create-react-app`, or just running the command `babel src -d lib`), it transforms all of your TypeScript files into regular old JavaScript files. This means that you can use TypeScript for its extra features and type checking, but still write code in plain old JavaScript if you prefer!

Hope this helps clarify things a bit! Let me know if you have any other questions or concerns.
