What is a module in javascript #javascript #module #function #shorts

In JavaScript, a module is a self-contained unit of code that encapsulates related functionality, variables, and data. It allows developers to organize their code into reusable and maintainable components, promoting modularity and separation of concerns. Modules provide a way to split code into smaller, manageable pieces, making it easier to understand, test, and collaborate on larger projects.

By using modules, JavaScript developers can define private and public members, control the visibility and accessibility of variables and functions, and prevent global scope pollution. This helps in avoiding naming conflicts and allows for better code organization.

In modern JavaScript, the standard for module implementation is the ES6 module syntax, which introduced the "import" and "export" keywords. These keywords enable developers to import functionality from other modules and export their own functionality for use in other parts of the application.
