What are the best practices for modular JavaScript?

Modular JavaScript involves organizing code into separate files or modules. Best practices include using ES6 modules, keeping modules small and focused, and using a module bundler like Webpack.

Can you explain why using ES6 modules is beneficial?

ES6 modules provide a clear syntax for importing and exporting code, which enhances readability and maintainability. They also support tree-shaking, allowing unused code to be eliminated during the build process.

What tools can I use for module bundling?

Popular tools for module bundling include Webpack, Rollup, and Parcel. Each has its own strengths, so the choice depends on your project needs.

How do I structure my project for modular JavaScript?

A common structure is to have a 'src' folder for your source files, with subfolders for components, utilities, and styles. This keeps your code organized and easy to navigate.
