Introduction

Modules

• a .js file
• can be imported in another .js file using require()
• can export values that are then imported, e.g. object, function, class, etc.
• can be package but doesn’t need to

Packages

• a package.json and a module that is referenced as main property in package.json, by default is called index.js
• packages are modules, but modules are not necessarily packages
• device-independent packages, need to be coded properly using built-in modules, e.g. path.join() instead of string cocatening file paths ❗️
