CommonJS vs ES Modules

Static analysis capabilities differ significantly: 1) ES Modules are designed to support static analysis due to their strict syntax and rules, 2) CommonJS's dynamic nature (require can be called conditionally) makes static analysis difficult or impossible, 3) ES Modules' static structure enables better tree-shaking and dead code elimination, 4) CommonJS modules must be executed to determine their exports and dependencies, 5) Static analysis in ES Modules enables better build optimization and tooling support, 6) CommonJS's dynamic nature provides more flexibility but sacrifices build-time optimizations, 7) This difference significantly impacts bundling efficiency and development tooling capabilities.
