What is treeshaking in Angular?

Tree shaking is a term used in the context of JavaScript and refers to the process of eliminating dead code from your final bundle. Dead code is code that is not actually used in your application and can safely be removed. The goal of tree shaking is to reduce the size of the final bundle and improve the performance of your application.

In Angular, tree shaking refers to the process of eliminating unused parts of the Angular framework from your final bundle. Angular is a modular framework, which means that you only need to include the parts of the framework that you actually use in your application. When you build your Angular application, the build process performs tree shaking and removes any unused Angular code, resulting in a smaller final bundle.

By reducing the size of the final bundle, tree shaking can help improve the performance of your Angular application by reducing the amount of JavaScript that needs to be downloaded and parsed by the browser. Additionally, by only including the code that is actually used, you can also improve the maintainability of your codebase and make it easier to understand and debug.

Overall, tree shaking is an important optimization technique that can help you improve the performance and maintainability of your Angular application.
