Tree shaking is an optimization technique used by JavaScript bundlers like Webpack and Rollup to eliminate unused code (dead code) from the final JavaScript bundle. It operates by analyzing the dependency graph of your application during the build process, identifying modules and exports that are imported but never actually used. This process is highly reliant on the static analysis capabilities of ES modules, which allow bundlers to determine imports and exports without executing the code. By effectively "shaking the tree" to make the dead leaves fall off, tree shaking significantly reduces the bundle size, leading to faster loading times and improved application performance. It's a crucial part of modern web development workflows for creating more efficient and lightweight web applications. More details: https://abcname.com
