Description: Tree Shaking is a term commonly used in JavaScript bundlers to remove unused code, optimizing the final package size. This process is crucial in modern web application development, where modularity and component reuse are fundamental. Dead code refers to code fragments that do not execute or are inaccessible during the application’s runtime, which can include functions, variables, or modules that are not used. Removing this code not only reduces the final file size, improving load times and user experience, but also facilitates code maintenance by eliminating unnecessary elements. Tools like Webpack and Rollup implement static analysis techniques to identify and remove this code, ensuring that only what is truly needed is included in the final package. Additionally, dead code elimination contributes to performance optimization by decreasing the amount of resources the browser must process, resulting in faster loading and better overall application efficiency.
