Before, I did a lot of H5 sharing, but whether it's a broad definition or profound, from this series, I want to start with the definition of H5, and summarize all the content and design methods I know about H5! It's a meaningful thing, and it's a very challenging thing, right here, I hope that if you can patiently read my share of the words must be to my deficiencies and lack of place to make evaluation, let us progress together for this emerging industry efforts! People often ask me

However, these do not really reflect the nature of an algorithm, and the result is to always stay on the surface of the problem. On the other hand, the re-teaching of thinking can make people develop from the nature of the problem, gradually analyze the habit of reasoning, rat
