How to Convert Common JS to ES6 Modules in JavaScript

If you are a JavaScript developer, chances are you’ve encountered both Common JS and ES6 module syntax in your coding journey. With the shift towards modern JavaScript, knowing how to convert between these two formats is essential. Particularly, this guide will help you understand how to convert code written in Common JS to ES6 modules with practical examples.

Understanding the Basics

What is Common JS?

Common JS is a module specification used in server-side JavaScript. It allows you to include modules using the require function. For example:

Why Convert to ES6 Modules?

There are several advantages to using ES6 modules:

Static Analysis: ES6 imports and exports can be statically analyzed, making bundlers more efficient.

Improved Performance: Modern JavaScript engines optimize ES6 module loading, which can lead to performance improvements in your applications.

Cleaner Syntax: The import and export syntax often leads to cleaner and more maintainable code.

Conclusion

Converting from Common JS to ES6 modules is straightforward and can significantly improve the quality of your code. With the shift towards native modules in modern JavaScript applications, it’s wise to familiarize oneself with this conversion process.

By applying the steps outlined in this post, you can successfully transform your Common JS code into ES6, enhancing the modularity and efficiency of your JavaScript applications.
