Build Pipelines and Bundling

Overview

Build pipelines transform your source code into optimized assets for browsers. Understanding this process is essential for performance optimization and debugging.

Why Bundling Exists

Browsers historically couldn't handle modern JavaScript development patterns:

// YOUR CODE: Many small files with imports
// src/
// ├── index.js (imports App)
// ├── App.js (imports Header, Main, Footer)
// ├── Header.js (imports Logo, Nav)
// ├── Nav.js (imports NavLink)
// └── ... 100+ files
