Frontend Performance Optimization

Speaking of performance optimization, I'm afraid I can't finish it for several days and nights. Today I want to talk about Web Front-end optimization, hoping to bring unexpected gains to everyone!

If we want to talk about front-end optimization, we have to mention Yahoo's yslow and Google's pagespeed. as long as their standards are concerned, they can be optimized very well. I will not talk about some simple web optimization, such as code compression, Gzip, and file integration. If you have any questions, please refer to Google Baidu, or leave a message!
