React Performance Optimization: Code Splitting

Code splitting and tree shaking are complementary techniques that can be used together to optimize bundle size. Code splitting divides your application into multiple chunks to load on demand, while tree shaking (or dead code elimination) removes unused code from your bundles. When used together, tree shaking ensures each chunk contains only the code that's actually used, and code splitting ensures you only load the chunks you need at a given time. This combination provides the most efficient loading strategy for your application.
