Modules in JavaScript

JavaScript modules are reusable, encapsulated pieces of code that can be imported or exported between files. They help organize large codebases into smaller, manageable parts, improving readability and maintainability. Modules also prevent variable and function name conflicts by creating separate scopes.

Exporting in JavaScript

Exports allow us to make functions, objects, or variables available to other modules. There are two main types of exports:

• Named exports: Allow us to export multiple items by name.

• Default export: Allow us to export a single item as the default for the module.
