The ES6 modules can help us to modularize our code by dividing the code into different modules(JavaScript files) and importing them into different files using the import statement wherever we need them. The module files can be saved using the .mjs extension to show that it is a JavaScript module. To import a module, you first need to export it using the export statement. There are two ways available in JavaScript to export a module.

• default export: It allows you to import a module using any name of your choice.
• named export: You can import a module using its name only. Otherwise, it will not be imported.
