3. Global Module Definition (UMD)

UMD aims to be compatible with both CommonJS ⁢and AMD, providing a single module format⁣ that works in various environments.

Syntax: Detects the habitat and uses the appropriate module​ loading mechanism.
Use Cases: ‍ Ideal for libraries intended to be used in both Node.js and browser environments.
Adaptability: ⁣ Offers the broadest compatibility.

Syntax: import ⁣and export keywords.
Use Cases: Increasingly ⁢becoming the preferred choice for⁣ modern JavaScript growth.
Browser Support: Native support is⁣ growing, but bundling tools may still be⁤ needed for older browsers.

How Module‍ Loaders Work:⁢ A Closer Look

Let's break ‍down⁤ the process ⁢of how a module loader typically operates. I've found that‍ understanding these steps⁤ is crucial for troubleshooting and optimization.

1. Configuration: You define a configuration file (often require.config.js ⁣ for RequireJS or⁣ a webpack.config.js for Webpack) that ‍specifies the module paths ​and dependencies.
2. Dependency Resolution: The loader analyzes your code to identify the modules and their ⁤dependencies.
3. Loading: It fetches⁤ the required modules, either from local files or⁤ remote URLs.
4. Execution: The loader executes the modules​ in⁢ the correct order, ensuring that dependencies are met before‌ a module is executed.
5. Caching: Many loaders cache modules to improve performance on
