This is a creation in Article, where the information may have evolved or changed. There is a significant difference between buffer and unbuffered Golang channel. I was naïve to think that there is a buffer and no buffer difference just unbuffered is the default buffer of 1 buffer In fact, it's completely wrong, and there's a big difference between unbuffered and buffered channel.

For example, there is a method to return a channel type, the general requirements of the operation can only be taken from here, then its purpose is only to store the type, if you do not care to save data at this time, the occurrence of panic causes the program to crash an exception. Then read the type of channel similarly. In fact, this is also for the security and robustness of the

: The return value is of type IEnumerator and has no parameters Yield keyword appears in the method There may be a lot of things that Ctrip can do, but the broader usage is to do something that needs to be delayed but not to get the program to lose its response during the delay. Because unity's logical processing is single-threaded, it can cause the experience to degrade in some places if the delay is not implemented by this method.I
