If effective, the following results appear:　　You do not care what these results mean, in short, these hints appear to prove that your GRUNT-CLI installation is successful.4.

, can generate professional and clean files from HTML descriptions. A lot of CSS needs to be introduced through HTTP requests (unless inline CSS is used), so you need to try to remove cumbersome CSS files, but pay attention to keep their important features.If your Banner, plug-in, and layout style are stored in different files using CSS, the visitor's browser loads a lot of files each time they access them. Although the existence of HTTP/2 reduces this problem, it will take a long time to

Ingenious use of ternary operators You can also use the ternary operator to make your code more optimized when you need to determine whether a value exists. Like what Obj=obj===undefined?

Haproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications, supporting virtual hosting, which is a free, fast, and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. The haproxy runs on the current hardware and can support tens of thousands of concurrent connections. and its operating mode makes it easy and safe to integ
