default class written in typescript in javascript

To use a default class written in TypeScript in JavaScript, you can follow these steps:

1. Create a TypeScript file, let's say MyDefaultClass.ts, and create a default class in it:

index.ts
export default class MyDefaultClass {
  constructor() {
    console.log("MyDefaultClass constructor called!");
  }
}

6 lines

2. Compile this TypeScript file to JavaScript using tsc command:

index.tsx
tsc MyDefaultClass.ts
22 chars
2 lines

This command will generate a JavaScript file named MyDefaultClass.js in the same directory.

3. In your JavaScript file, you can import this default class using import statement:

index.tsx
import MyDefaultClass from "./MyDefaultClass";

const myDefaultClassInstance = new MyDefaultClass(); // Output: MyDefaultClass constructor called!

Note that, in JavaScript, you don't need to specify the file extension (.js) when importing a module.

That's it! You can now use your default class written in TypeScript in your JavaScript code.
