Methods for front-end optimization of website performance mode include "compressing and merging resources", "image optimization", "using caching", "asynchronous loading", "reducing redraw and reflow", "using CDN", " Nine types: "Remove unnecessary plug-ins and third-party libraries", "Responsive design" and "Use modern technologies": 1. Compress HTML, CSS and JavaScript files to reduce file size; 2. Use appropriate image formats, And compress the images; 3. Use browser cache and server cache to store pages and resources, etc.

Front-end optimization is an important part of improving website performance. Here are some common methods for front-end optimization:
Compress and merge resources: Compress HTML, CSS and JavaScript files to reduce file size while merging multiple files into one. Reduce the number of HTTP requests.
Image optimization: Use appropriate image formats and compress images to reduce image file size and improve page loading speed.
Use cache: Use browser cache and server cache to store pages and resources, reduce repeated network requests, and speed up page loading.
Asynchronous loading: Delay loading of non-critical resources and use asynchronous loading to load JavaScript files to improve the loading speed of the first screen of the page.
Reduce redrawing and reflow: By optimizing CSS and DOM structures, we can reduce redrawing and reflow operations during page rendering and improve page rendering performance.
Use CDN: Distribute static resources through a content delivery network (CDN), allowing users to obtain resources from closer servers and reduce loading time.
Remove unnecessary plug-ins and third-party libraries: Delete unused plug-ins and third-party libraries to reduce web page size and improve loading speed.
Responsive design: Use responsive layout to ensure that the website performs well on different devices and improves the experience of mobile device users.
Use modern technologies: Use new web technologies, such as using WebP format images, adopting the latest CSS and JavaScript features, etc. to improve performance.
Through the above front-end optimization methods, you can effectively improve the loading speed and performance of the website, improve the user experience, and thereby enhance the competitiveness of the website.
