# The management rules of each end need to be learned patiently
uni-app is not difficult to learn, but we noticed that many newcomers are impatient when adapting to the constraints of each platform.
For each end, there are management rules for each end, which is not something that uni-app can smooth out on a technical level:
For example, the browser on the H5 side has cross-domain restrictions;
For example, the WeChat MiniApp will require HTTPS links, and all server domain names to be connected to the Internet must be assigned to the WeChat whitelist;
For example, on the App side, iOS is very strict on privacy control and virtual payment control;
For example, various compatibility differences between App, Android, and domestic roms, especially because Google services are blocked, resulting in the development of push, positioning and other chaotic pits;
Being patient and not impatient is not the only factor for success, but it is the foundation for your long-term technical journey.
# uni-app's underlying framework implementation principle and optimization strategy (advanced)
Through evaluation comparison,we know that the performance of uni-app is better than other MiniApp development frameworks, but what is the underlying principle?
This video is to explain the underlying implementation ideas and optimization strategies of the uni-app framework: How to achieve high performance in the uni-app framework
