Importing and Exporting Modules

Hello, students! In the previous topic, we learned about arrow functions, destructuring, and template literals.

Here, let’s learn about importing and exporting modules.

Modules are a way to organize your code into reusable units.

With module importing and exporting, you can split your code into multiple files, making code maintenance and reuse easier.

Importing

To import a module, use the import keyword.

Here’s an example of importing a module:

import myModule from './my-module';

This code imports the my-module module.

You can import a module to get a variable, a function, or an object.

For example, the following code imports the my-module module to get the myVariable variable:

import { myVariable } from './my-module';

Exporting

To export a module, use the export keyword.

Here’s an example of exporting a module:

export const myVariable = 'Hello, world!';

This code exports the myVariable variable.

You can export a variable, a function, or an object.

For example, the following code exports the my-module module with the myVariable variable:

export { myVariable };

Conclusion

In today’s topic, we learned about importing and exporting modules.

These techniques can make React development more efficient and enjoyable.

In the next topic, we’ll learn about rendering in React.

Rendering is the process of creating the user interface for your React application.

In the next module, we’ll learn about the different ways to render your React application.

I hope you’re excited to learn more about rendering in React!
