The advantages of lazy loading in routing include reducing initial loading time, reducing server load, optimizing page performance and improving user experience. The disadvantages of lazy loading of routes include the need for additional engineering development, increased code complexity, delayed loading time and the need for browser support. Route lazy loading is a method of optimizing web application performance by loading relevant code and resources on demand when the user navigates to a specific route to reduce initial load time and reduce server load.

Route lazy loading is a method of optimizing web application performance by loading relevant code and resources on demand when the user navigates to a specific route to reduce initial load time and reduce server load. The advantages and disadvantages of lazy loading of routes are as follows:
Advantages:
1. Reduce initial loading time: Lazy loading only loads the code and resources required for the current route, rather than loading the entire application at once . This can greatly reduce the initial loading time, improve the response speed of the page, and improve the user experience.
2. Reduce server load: Lazy loading only loads code and resources from the server when needed, reducing the load on the server. Compared with loading the entire application at once, lazy loading can effectively reduce the resource consumption of the server and improve the performance and scalability of the server.
3. Optimize page performance: Lazy loading can load different codes and resources according to different routes of user navigation, which can prevent users from downloading unnecessary codes and resources. By loading only the content you need, lazy loading reduces the size and complexity of your page, thereby improving your page's loading speed and performance.
4. Improve user experience: Lazy loading allows users to see the content of the page immediately during navigation without feeling impatient due to long loading times. This can improve user satisfaction and retention, and increase user usage and exploration of the site.
Disadvantages:
1. Requires additional engineering development: Implementing lazy loading of routes requires careful division and configuration of the application's routes, which requires additional engineering development. For large and complex applications, this can increase development complexity and difficulty.
2. Increase the complexity of the code: Lazy loading requires modularization and on-demand loading of the code. This can increase the complexity of your code, especially when dealing with dependencies and asynchronous loading.
3. Lazy loading time: Lazy loading will cause part of the page to be delayed during user navigation. While this can improve initial load times, users may see some blank pages or loading indicators during navigation, which may reduce user satisfaction.
4. Requires browser support: Lazy loading relies on browser support, especially support for modularization and dynamic loading. Lazy loading may not work properly if the user is using an outdated browser or a browser that does not support these features.
To sum up, routing lazy loading has many advantages in improving web application performance and user experience. Although it requires additional engineering development and complex processing of code, lazy loading can reduce initial load time, reduce server load, and optimize the performance and user experience of the page.
