Working with JavaScript Modules

When writing web applications, JavaScript code can rapidly become difficult to maintain and understand. In this course, you will learn how to use modules to break up your code into manageable pieces that are easier to work with.

At the core of JavaScript is a thorough knowledge of Modules. In this course, Working with JavaScript Modules, you’ll learn how to break your code out into modules in a logical way and use those modules in your application. First, you’ll learn what modules are and why you should use them. Next, you’ll explore how to import and export code from modules. Finally, you’ll discover how to use those modules in a real-world application. When you’re finished with this course, you’ll have a foundational knowledge of modules that will help you as you move forward to build easier to maintain JavaScript applications. Software required: JavaScript.
