My JavaScript Learning Journey: CommonJS vs ESM,Design Patterns

JavaScript Architecture, Design Patterns, Memory Mechanics.

Today I learned about core JavaScript architecture, modules, design patterns, memory mechanics.

Understanding how JavaScript handles files, memory, and software design makes it much easier to write clean, scalable, and maintainable applications.

1. CommonJS (CJS) vs. ES Modules (ESM)

JavaScript uses modules to split code across multiple files and avoid polluting the global scope.
